Not really a fact, rather a general opinion that would be comparable to saying "Dogs are more effective than cows". Modern helmets come in a variety of shapes, sizes, and grades when it comes to protection against bullet resistance, blast resistance and how comfortable it is to wear.
I know it's been mentioned, but these helmets are meant to stop small things going very fast, not heavy things going slowly. Kevlar has AMAZING tensile strength, but it literally has the compressive strength of cotton, because like cotton it's a fabric. You don't need to stop a bullet from pushing in the helmet, you need to stop the bullet from getting through the helmet. That's where kevlar obliterates steel, particularly for its weight.
If that's true, why did the pointy side of the hammer break the kevlar helmet surface so easily when hit, but practically made no dent on the old steel helmet? I don't know, man...
@@deafinki Because that's literally what I said, it has poor compressive strength. A hammer isn't a bullet or a piece of shrapnel. The hammer is slow and heavy (comparatively speaking), it breaks the polymer holding the helmet together because it has more momentum than a piece of shrapnel. However, it didn't go through the kevlar, nor would piece of shrapnel.
@@deafinkibecause when you hit with hammer it continues applying force way slower because of your hand fixing it on one place. If you stop applying force as fast as bullet will, it won't break as much. Also, there's a difference between durability of helmet and how much it protects. Because Kevlar is fabric, it's way better at absorbing force compared to steel which is more likely to move because of serious impact, and that's at least distraction, maybe even head damage if it straps won't distribute force enough.

@@macbird-lt8deWho tf are you trying to "roast" right now? And for what reason? You were practically talking to no one, it might've as well have been a wall you were talking to.
I can explain why the old helmet did 5x better than the new one. Steel helmets, like the old one, are obviously made of steel, and steel is extremely rigid and it's point of bending is quite high compared to other things. However, the new one was most likely plastic and Kevlar. Plastic, is self-explanatory while Kevlar, is more complex. Kevlar is extremely strong in stopping fast impact things, like bullets. But once you get slow in it, like with a knife, the fibers of the Kevlar slowly wear apart and break, like what was seen in the video. Be on watch for enemies with hydraulic presses though.
Having witnessed several high velocity round impacts on aramid and Kevlar helmets; the kit does its job beautifully. The round enters and cuts through several layers before being caught between two layers on the helmet. The round then follows the layer and tracks around the helmet before either flying out around the back or, running out of steam and sticking in the helmet. Amazing bits of kit. Lightweight, phenomenal protection and gives confidence to those wearing it.
I will take some of the older kevlar helmets over that thin steel wall soviet helmet anyday. In fact I find the kevlar helmet superior to the more lighter modern helmets with the hear protection holes cut out of them on the sides.
...the press is an interesting test, and you're spot on above, but if someone was dropped straight down from 10,000 feet and impacted a flat hardened steel surface, the steel helmet is the choice!
Awesome Yeah, that Kevlar helmet is a number of layers pressed together with PVB resin. The press doesnt do it justice. Seeing how it protects against shrapnel and rounds brings a whole new appreciation for the modern aramid helmet.
In 1967, my cousin Charles was on his second tour in Vietnam with the 1st Cav. He was riding in the back of a Jeep when he took a round in his head, thru his steel pot. The round entered his helmet and circled inside , destroying his skull. I served with the 25th and 3rd Infantry 4 years later. This helmet comparison brought these memories back.
The kelvar is the more suitable choice. The reason is that it is supposed to deflect objects, bullets, and protect your head. Take, for example, a bicycle helmet. It is not supposed to stay together but absorb some of the pressure. When you use just steal, it won't break, but it won't absorb any of the pressure/energy. Though the kelvar isn't meant for slow pressure, it is meant for fast, small objects, which is shown in the beginning. Also, the kelvar has cushions that protect the skull and prevent sharp objects to poke through. (Feel free to do your own research. Have a wonderful day or night :D)
Your first sentence makes no sense. It's clearly not more suitable. Did you see the video? Suitable for what? There are lots of uses for these so what do you mean? Suitable for what? Suitable for bike accidents or bullets? Kevlar is not more suitable for everything.
I am impressed by the workers helmet. You would imagine that it is just to protect you from small objects like tools or such falling down from a construction, like it doesn't look super robust with all that plastic. But from how much weight it can take it looks like it could protect your head even if a building collapses on you.
C’est vrai, moi aussi je ne pensais pas que ce genre de casque avait une telle résistance ! Malgré tout ce test est très limité pour rendre compte de la réelle efficacité d’un casque .
Luckily, if a soldier was ever put in a situation where the ceiling was slowly applying pressure to the helmet from above. The body would give in first leaving the helmet intact.
The kevlar helmet is probably by far the best at protecting against gunfire. Though it has relatively weak compression strength, it is layered to be more effective at stopping bullets. The steel helmet however might be worse against bullets, even a 9mm could potentially pierce it if it didn't get deflected.
@Frozenmonkey2 which is the point I'm trying to make, a kevlar helmet is better at stopping bullet impacts in their tracks, while steel is prone to deformation and puncturing. I'm not trying to start an argument about damn military helmets
I remember when the Kevlar first came out. We were shown one of each shot. The steel pot only had a dimple in it. The Kevlar had a splintered hole through it. I thought to myself, "why ?" Of course I really didn't know if the same weapon had been used on both. I really did enjoy how much more comfortable the Kevlar than the steel pot. Lot lighter , the steel pot always gave a person a tension headache. The great thing about the steel pot was that you could turn it over and heat up water if needed.
Kevlar is meant to be lightweight and protect you from bullets and small projectiles. It makes sense it ressists much less pressure. The old helmet might be better at protecting against stunning objects since it's made of metal, but maybe not so much against bullets. Depends on the caliber and the distance. Plus, I'm sure it weights way more than the kevlar one. The police one is only to denfend against stunning objects like sticks and stuff rioters might throw at them. Therefore is made with lighter materials and it takes less pressure to crush it. All in all, more ressistant to pressure doesn't necessarily mean better.
Helmets are meant to protect against 2 main things: punctures and blunt impacts. The shell strength will help with the punctures, whereas blunt impact protection is all about prolonging the deceleration time of the foreign object in order to reduce the concussive forces (ex. 1000kg force over 1 second, vs 1000kg over 10 seconds). Multilayer kevlar outshines high-carbon steel in both of these areas, although it has lower overall strength against crushing forces.
Well outlined. Like...unless ur laying on ur side and the tank is rolling over your helmet only lol these compression tests are useless because your neck would snap looooooooooooong before the weakest helmet fails
Regardless of which helmet you're wearing, they aren't designed for being under that much pressure, they were made to deflect objects. Anything that falls on you weighing 1000 lbs is going to kill you, whether you're wearing a helmet or not.
The older steel helmets were really meant to deflect shrapnel and small fragments as well as keep the worst of the elements off your head. A Full metal jacket steel core round is gonna punch right through. I tested with an SKS and an old GI helmet and the bullets turned the helmet into a cheese grater.
I know it doesnt mean anything as this isnt what the helmets are designed for, but it's still really interesting to see how they deform and how much pressure it takes to do that!
I'd be more interested in seeing how they hold up to bullets and shrapnel....I don't think the helmets are designed to protect against getting slowly crushed.
1:29 Work Helmet - 668kg 2:33 Old Army Helmet -10,212kg 4:00 Newer Army Helmet - 1,970kg 5:14 Police Helmet - 1,815kg You're welcome, everyone that wants to skip to the good parts
WWII and other wars, soldiers liked to use their steel outer helmets as multi-purpose utility buckets. Boil water, cook rations, etc. my dad was a cook in the seabees and had some interesting WWII stories.
Well not a surprise that newer helmets are not as tough as older versions, newer helmets wasn't designed to being crushed under pressure, however newer versions are great in shock absorption.
Ironworkers, steel beams/tall buildings, traditionally wear kevlar hardhats. A couple guys were lifting one end of a truss (Phillips Arena) with large porto power. It kicked out fell about 35' and hit me in the head. Large crease in the hardhat. I had a headache for a couple days. Years later I'm the field safety manager for a large erection company. Used the hardhat for some show and tell, they do work
That's pretty much what I expected although the old steel one was better than I expected, but I think you'll find the Kevlar one will prevent bullets whereas the others won't do so well and this is their main purpose, not preventing crushing.
Also important to note for combat effectiveness is the amount of pressure that's absorbed by the helmet and not just how durable the helmet is. Metal will be designed to crumple in some designed situations to allow for safety further in.
The data from this video reveals the actual strength of the forged metal helmet. It's deflective, bendable and dentable to a point which buffers the impact of projectiles yet strong as cast iron before shattering. Very impressive alloy material.
yeah impressive indeed btw i know some of you guys hate self promoters, but if you're really interested to check my song called end of the day out, i'd be glad tho. thank you :)
@@thomasmonahan1675 but can your brain withstand the concussion? Steel helmets weren’t designed to stop bullets, they were to stop troops being taken out by shrapnel and debris, the minor hits that would incapacitate a man with a bare head.
@@python27au helmets distribute a conencrated force on a wide area so yes it will definetely protect you from concussion. Youd have to be hitting someone incredibly almost impossibly hard to give them a concussion with a helmet on i believe
im glad everyone understands the kevlar is just as affective and more lightweight. it actually may even deflect bullets more efficiently and doesnt dent like the old one does.
It seems less effective if you compare weapons of 1968 and 2008 there's a lot of difference that goes (weapons are more advance now). But as someone mentioned the helmets are not made to handle that much weight rather designed to prevent the damage, so you seems to right about effective bullets deflection
@@vaibhavsharma4944 I fully expected that if the old one "won" there would be a million people screaming in the comments how it was better. Glad that didn't happen and people are using common sense and logic.
@@vaibhavsharma4944 If you're talking about small arms technology then you'd be wrong. The United States still uses the same cartridges that it did in 1968. While there have been iterative advancements on small arms it's not that far of a developmental leap from 50 years ago. A well designed Steel Helmet would perform just as effective at stopping handgun rounds as a Kevlar Helmet. Although Kevlar is lighter and doesn't dent. Body armor has developed faster than small arms.
There are many challenges bringing a hydraulic press to the battle field. Even more challenging to persuade enemy troops to stick their heads into the machine for a nice compression test.
@@29brendus Not everyone can afford to buy one... it's easy to say that when you have one or when you are rich... unfortunately, if you knew what the world was hiding... Anyway, it's not interesting
Interesting test but totally beside the point: Each helmet is designed for a different purpose and its resistance to compression proves not how well it has been built to achieve its intended purpose.
It's obvious that modern helmet is way more comfortable and have other additional support and purpose too but the old one with less technology and yet so strong as compare to new ones that comes out from hi-tech factory. That itself is a shame. Just my opinion 😅
@@Tholin-tm7ps keep in mind they normally would have kevlar around the helmet, the purpose for the helmet is to make sure that it absorbs impact and also prevent bullets from fully penetrating
Yes a steel helmut will dent but it can be hammered back into shape with little loss of strength! I think a helmut designed with both an outer layer of steel and an inner layer of kevlar with a one-inch gap between would be more effective at stopping bullets as the steel would help blunt and slow down the round, the gap would allow for sideway dispersion of energy and the kevlar would act as a shrapnel shield. Perhaps a similar honey-combed version with rubber balls evenly spaced in the gap would also cut down on the transferred energy to the head. I think that body armor with a locking ring for supporting the outer steel shell to place the weight on the shoulders instead of the neck and the kevlar shell would be directly attached to the head giving greater bullet resistance with less weight on the neck. I believe this would be superior protection especially for the neck. In low threat areas the outer shell could be left off for comfort! Other improvements are possible! Also, helmets are used for other things such as a (steel pot anyway) a vessel to heat water in, a improvised digging tool, a not-too-comfortable seat. etc.
Steel seemed to have been the best choice at the time, taking into account that the army was only thinking about blunt force at the time and not all the scientific implications of aerodynamics a bullet or high speed projectiles have, like shrapnel, and that Kevlar was a lot better for that, since it has many layers that the projectile has to go through, and that steel has only one, but they didn't realize that until the '70s. This is why the steel helmet performed better on this test.
@@theisFandy the main purpose of the steel helmet was to protect you from falling debris from artillery while in a trench, against direct fire you would strap on the additional M16 Stirnpanzer plate
@@TrueFork true. But another purpose was to reduce the death from bullets. Yes, the helmet could help you to survive even shot (from specific angle). There was interesting story from I ww. I believe British army considered to come back to the leather hats or whatever they been called as there was more injuries than before. But they didn't took into consideration that more injured was equall to less dead. Because of that they stayed and steel became the standard in the next wirld war. Why there was no cevlar helmets? Fkn technology gap. Simple.
You are wrong. The aerodynamic were very well known even in 20s. The problem was the lack of technology. That's why there was no cevlar/bulletproof jackets among the masses of soldiers during II WORLD war. There was no mass production cost effective technology. The aerodynamics of bullets and the rest was extremely well known, especially when tanks were improved in the 30s. The steel helmets were the only solution as we're relatively cost effective and possible to mass production. At certain angle the bullet would ricochet from the helmet possibly leaving you just with light wound.
@@theisFandy El gringo te cuenta que los cascos de esos años eran toscos y no pensados con los conocimientos físicos actuales de aerodinámica, transferencia de energía y todas esas weas, por lo que los cascos eran ultra pesados y no necesariamente más efectivos que los modernos.
The helmets aren't designed to protect your head from being driven over by a tank. Their ability to protect against shrapnel or glancing bullets isn't going to be measured by a press. From what I've heard the biggest drawback of the kevlar helmet is you can't use it to cook soup in your foxhole.
I remember when these came out. They were not popular. On the bright side, they were lighter and more comfortable and cooler than the old steel pots, But you couldn’t use them to heat up water or do a lot of things that you could do with the older pots
On range we fired several 7,62x51 out of g3 battle rifles on areound 100M on a steel helmet using standard NATO ammunition. All hits went through like a hot knife through butter. Especially one round that only hit the most outer edge of the steel helmet, made a scorch mark for over a inch (2,5cm), denting the steel inward, then entered the helmet at nearly no angle to the steel, and then also changed course inside the helmet afterwards. Never tried this with kevlar helmets though, but a steel helmet isn´t any good for more than protecting from debris flying around your head.

Must be PTSD because I believe that a Vietnam helmet....thats why it doesn't make sense, its much easier to hide a hydraulic press booby trap in the jungle than in the battlefields of WW2.
The "worker helmet" is funny, because hard hats are meant to redirect damage. That's why they fall off your head so easily. If they just stopped falling objects dead, the force would go to the wearer's necks.
Not true. If something heavy were to hit your head and your hard hat was on tight, your head would be pushed and the object would land on your shoulders or barely miss you. While yes they redirect damage, they aren’t made to fall off. That’s why good quality hard hats are adjustable to fit tightly on your head. They also protect your head from hitting things yourself, like a low beam or ceiling and stop projectiles like blades or fragments. For example, lay a hard hat down and try to hit it with a hammer. The hat will just keep moving, like your head would if you had the hard had on tight, as you should
@@MrSpecOps Don't be so harsh. That's also the reason modern car airbags have a flight mode. When you crash they fly away to better protect you from the bus you plowed into by 'redirecting' the crash from them to your shoulders and face that are now unprotected Also the reason why boxers 'protect' their vulnerable gluteus by taking punches to the much sturdier face
@@snakevenom4954 I mean, you're right, they aren't made to fall off super easily, but they also don't strap under your chin. They aren't meant to *never* fall off.
Yall right the name should on been a dead giveaway. I searched that 73 percent of indians (non American) have helmets and hydo presses in their bed room for kink purposes
It's clear that the kevlar soldier helmet is designed to absorb impact energy by deformation. The steel helmet took 10 tonnes, and that's far more than any neck or skull can take, and only the harness inside that helmet absorbs energy from an impact, while with the newer helmet the harness and the shell both absorb energy.
steel may took 10 tonnes with all that massive surface, but bullet only needs to make a small hole on small surface area to get the job done. Steel helmets were basically second scull if it comes to firearms - just a decoration, morale boost. Protected only from farm weapons and really weak shrapnels
@@spicydiarrhea5662 They were hardly just a decoration/morale booster, they were designed to protect against shrapnel mainly from artillery and grenades, and they did that well. Most steel helmets are also strong enough to stop things like pistol rounds, but neither old nor new helmets really help against rifle rounds.
Don't. A single drop from 4-5 feet renders them useless. They're meant to handle one impact and that's it. Impact force is completely different than compression force.
Though the Kevlar would appear to give you less protection, it's actually better protection as it will dampen the blow you received. While the steel one will be far better at transferring the energy to the wearer.
Also, I suspect the weight they hold is very different, making for a striking difference in comfort after prolonged wear. Which might not mean much, but when you're a soldier that has to wear it all day for days at a time, it's all the difference it takes for your own body to resist longer in harsh conditions.
It’s like with old vs. new cars. Old steel carosseries will shine like a star after a crash while new cars will be crumpled up to high hell, but what we forget that inside the shiny steel box _you’d_ be crumpled up to high hell.
Just had the image of a guy running over no man's land in ww1 with a hydraulic press in his arms then just yeeting the entire thing into the enemy trench
I swear the police helmet had a sigh of relief thinking it was over and that it survived only to be repositioned and have its dreams hydraulically pressed
Kevlar is meant to be more for shock absorption, like the vest it's meant to divert kinetic energy from a bullet to be at a non lethal speed. Meanwhile a steel helmet is not shock absorbing, but because it is solid steel it will deflect any kind of projectile, however the shock and the kinetic energy will remain, so you can possibly have a concussion but at least you won't have a hole in your head.
I don't know about the steel helmet defecting any kind of projectile 🤔 a rock maybe lol Didn't steel helmets make death more likely as the bullet would go through one layer, stay inside and bounce around rather than pass all the way through?
@@danellboy5757 Depends on the range and bullet. I saw a WW2 training video where they demonstrated the effects of different calibers at different ranges on a German helmet. At a long enough range the helment would stop a pistol or carbine round, but nobody would choose those at long range.
@@paradyne1T101 no it’s because they made old helmets to not break at all but the newer ones are lighter and are better at their job deflecting bullets
@@krishnakode3894 No, because when you look at the other uploads like the old style steel hammer vs modern, old style concrete vs modern..etc it's painfully obvious that modern day comes up lacking in strength, quality, and durability which is a reflection on today's "make it cheap but charge a fortune for it" practice that is the blueprint of today's corporations ..I would trust you explanation about the modern helmets being better at deflecting bullets had he actually fired ammunitions at them as a proof test

Even when the breaking point is much higher at the steel helmet, i consider the kelvar one as the better protection against real threats because of the Absorption features and layered build.
This reminds me of a semi-related fun fact. I wanna say it was the British army, but it was found that shortly after switching from leather helmets to metal ones, the number and rate of head injuries from combat dramatically increased. It seems counterintuitive, but this was actually a good thing since those with leather helmets rarely suffered head injuries as fatalities were not categorized as injuries.
Fun fact: roller blade wrist guards have a plastic insert that stops the wrist from bending too much during a FOOSH (falling on outstretched hand) injury - the most common fall for beginners. When they first started making the wrist guards, people would complain that the plastic insert broke when they fell over. A few companies switched to metal inserts. Then the companies found that people's wrists were breaking because the metal wouldn't break and absorb any of the force. So they went back to plastic.

Ww2 helemets were mostly against low impact fragments, low speed bullets, and basic "don't hit your head on stuff". They were cheap, easy and fast to produce in big quantities and we're more useful than not. They would deflect bullets and fragments but if pierced (if that surface was broken) you would be injured or dead. Modern ones can deflect but are able to absorb the impact, they would contain the bullet or fragments and some of the kinetic energy, although you would feel like getting hit in a head by Mike Tyson at least your would live. Biggest difference would be at around 90deges of impact(less likely to deflect)
It's kinda like classic cars and modern cars. Classic cars had big solid steel frames and bumpers, that at low speeds, you'd deflect most things, but high speed crashes are lethal. Modern cars have plastic bumpers, built to crumple and absorb kinetic energy.
I'd like to see how the helmets hold up to different caliber rounds, the hydraulic 'squash' was fun to watch but no one runs into a hulk smash wearing them! 🤣
the hydrolic press only proves the kevlar it is better since instead of pulling appart and ripping under high presure it crumpled and stayed intact meaning there is a good chance that instead of ripping appart after getting hit by a bullet or letting one through it would rather catch it and transfer all of the kenetic energy to the helmet

I know it's been mentioned, but these helmets are meant to stop small things going very fast, not heavy things going slowly. Kevlar has AMAZING tensile strength, but it literally has the compressive strength of cotton, because like cotton it's a fabric. You don't need to stop a bullet from pushing in the helmet, you need to stop the bullet from getting through the helmet. That's where kevlar obliterates steel, particularly for its weight.
If that's true, why did the pointy side of the hammer break the kevlar helmet surface so easily when hit, but practically made no dent on the old steel helmet? I don't know, man...
@@deafinki Because that's literally what I said, it has poor compressive strength. A hammer isn't a bullet or a piece of shrapnel. The hammer is slow and heavy (comparatively speaking), it breaks the polymer holding the helmet together because it has more momentum than a piece of shrapnel. However, it didn't go through the kevlar, nor would piece of shrapnel.
@@deafinkibecause when you hit with hammer it continues applying force way slower because of your hand fixing it on one place. If you stop applying force as fast as bullet will, it won't break as much. Also, there's a difference between durability of helmet and how much it protects. Because Kevlar is fabric, it's way better at absorbing force compared to steel which is more likely to move because of serious impact, and that's at least distraction, maybe even head damage if it straps won't distribute force enough.

I can explain why the old helmet did 5x better than the new one.
Steel helmets, like the old one, are obviously made of steel, and steel is extremely rigid and it's point of bending is quite high compared to other things.
However, the new one was most likely plastic and Kevlar. Plastic, is self-explanatory while Kevlar, is more complex. Kevlar is extremely strong in stopping fast impact things, like bullets. But once you get slow in it, like with a knife, the fibers of the Kevlar slowly wear apart and break, like what was seen in the video. Be on watch for enemies with hydraulic presses though.

Having witnessed several high velocity round impacts on aramid and Kevlar helmets; the kit does its job beautifully. The round enters and cuts through several layers before being caught between two layers on the helmet. The round then follows the layer and tracks around the helmet before either flying out around the back or, running out of steam and sticking in the helmet. Amazing bits of kit. Lightweight, phenomenal protection and gives confidence to those wearing it.
I will take some of the older kevlar helmets over that thin steel wall soviet helmet anyday. In fact I find the kevlar helmet superior to the more lighter modern helmets with the hear protection holes cut out of them on the sides.
...the press is an interesting test, and you're spot on above, but if someone was dropped straight down from 10,000 feet and impacted a flat hardened steel surface, the steel helmet is the choice!
Glad others are willing to wear that, personally though I'm sticking with just a baseball cap worn in this country
Awesome
Yeah, that Kevlar helmet is a number of layers pressed together with PVB resin.
The press doesnt do it justice.
Seeing how it protects against shrapnel and rounds brings a whole new appreciation for the modern aramid helmet.

In 1967, my cousin Charles was on his second tour in Vietnam with the 1st Cav. He was riding in the back of a Jeep when he took a round in his head, thru his steel pot. The round entered his helmet and circled inside , destroying his skull. I served with the 25th and 3rd Infantry 4 years later. This helmet comparison brought these memories back.

"Do not repeat at home what you saw in this video"
Because everyone has a hydraulic press and two army helmets at home.
who doesn't?
Not only that but a police grade riot helmet
you don't ......?
Well the helmets featured in the video weren’t US army helmets
"Then you saw in this video" get it right
The kelvar is the more suitable choice. The reason is that it is supposed to deflect objects, bullets, and protect your head. Take, for example, a bicycle helmet. It is not supposed to stay together but absorb some of the pressure. When you use just steal, it won't break, but it won't absorb any of the pressure/energy. Though the kelvar isn't meant for slow pressure, it is meant for fast, small objects, which is shown in the beginning. Also, the kelvar has cushions that protect the skull and prevent sharp objects to poke through. (Feel free to do your own research. Have a wonderful day or night :D)
We all know this. However the steel helmet was impressive nonetheless considering the era. Old school mil spec produced amazing gear for our boys
Bro that thing dose not survive 2000 kg
Your first sentence makes no sense. It's clearly not more suitable. Did you see the video? Suitable for what? There are lots of uses for these so what do you mean? Suitable for what? Suitable for bike accidents or bullets? Kevlar is not more suitable for everything.
I am impressed by the workers helmet.
You would imagine that it is just to protect you from small objects like tools or such falling down from a construction, like it doesn't look super robust with all that plastic.
But from how much weight it can take it looks like it could protect your head even if a building collapses on you.
C’est vrai, moi aussi je ne pensais pas que ce genre de casque avait une telle résistance !
Malgré tout ce test est très limité pour rendre compte de la réelle efficacité d’un casque .

Luckily, if a soldier was ever put in a situation where the ceiling was slowly applying pressure to the helmet from above. The body would give in first leaving the helmet intact.
Would arguably be a worse fate with the helmet on lol
Much smart
@@theredcinder7437 yeah- lol

Id think that you'd want your head to go first before your body.
The kevlar helmet is probably by far the best at protecting against gunfire. Though it has relatively weak compression strength, it is layered to be more effective at stopping bullets. The steel helmet however might be worse against bullets, even a 9mm could potentially pierce it if it didn't get deflected.
@Qefna Ija oh yeah?
True
It's like more strength per cm than strength in overall structure
@Frozenmonkey2 which is the point I'm trying to make, a kevlar helmet is better at stopping bullet impacts in their tracks, while steel is prone to deformation and puncturing. I'm not trying to start an argument about damn military helmets
@Frozenmonkey2 would u like to have steel pushed into ur skull or fiber
The Kevlar helmets are still not to good at protecting against direct hits from bullets😂 they’re more for shrapnel
I remember when the Kevlar first came out.
We were shown one of each shot. The steel pot only had a dimple in it. The Kevlar had a splintered hole through it. I thought to myself,
"why ?" Of course I really didn't know if the same weapon had been used on both. I really did enjoy how much more comfortable the Kevlar than the steel pot. Lot lighter , the steel pot always gave a person a tension headache. The great thing about the steel pot was that you could turn it over and heat up water if needed.
Seems like you could also put a house's foundation on top of it. 😅
Kevlar is meant to be lightweight and protect you from bullets and small projectiles. It makes sense it ressists much less pressure. The old helmet might be better at protecting against stunning objects since it's made of metal, but maybe not so much against bullets. Depends on the caliber and the distance. Plus, I'm sure it weights way more than the kevlar one. The police one is only to denfend against stunning objects like sticks and stuff rioters might throw at them. Therefore is made with lighter materials and it takes less pressure to crush it. All in all, more ressistant to pressure doesn't necessarily mean better.
Helmets are meant to protect against 2 main things: punctures and blunt impacts. The shell strength will help with the punctures, whereas blunt impact protection is all about prolonging the deceleration time of the foreign object in order to reduce the concussive forces (ex. 1000kg force over 1 second, vs 1000kg over 10 seconds). Multilayer kevlar outshines high-carbon steel in both of these areas, although it has lower overall strength against crushing forces.

So long as they stop shrapnel I didn't care how much weight it could take.
@@keuschkacey good news, the newer helmets also resist punctures better.

Ironworkers, steel beams/tall buildings, traditionally wear kevlar hardhats. A couple guys were lifting one end of a truss (Phillips Arena) with large porto power. It kicked out fell about 35' and hit me in the head. Large crease in the hardhat. I had a headache for a couple days. Years later I'm the field safety manager for a large erection company. Used the hardhat for some show and tell, they do work
That's pretty much what I expected although the old steel one was better than I expected, but I think you'll find the Kevlar one will prevent bullets whereas the others won't do so well and this is their main purpose, not preventing crushing.
Also important to note for combat effectiveness is the amount of pressure that's absorbed by the helmet and not just how durable the helmet is. Metal will be designed to crumple in some designed situations to allow for safety further in.

A well designed Steel Helmet would perform just as effective at stopping handgun rounds as a Kevlar Helmet. Although Kevlar is lighter and doesn't dent. Body armor has developed faster than small arms.

@@Tholin-tm7psthe new "plasticy" helmets are designed to absorb as much impact as possible instead of your head to keep you alive.
@@Tholin-tm7ps keep in mind they normally would have kevlar around the helmet, the purpose for the helmet is to make sure that it absorbs impact and also prevent bullets from fully penetrating
Yes a steel helmut will dent but it can be hammered back into shape with little loss of strength! I think a helmut designed with both an outer layer of steel and an inner layer of kevlar with a one-inch gap between would be more effective at stopping bullets as the steel would help blunt and slow down the round, the gap would allow for sideway dispersion of energy and the kevlar would act as a shrapnel shield. Perhaps a similar honey-combed version with rubber balls evenly spaced in the gap would also cut down on the transferred energy to the head. I think that body armor with a locking ring for supporting the outer steel shell to place the weight on the shoulders instead of the neck and the kevlar shell would be directly attached to the head giving greater bullet resistance with less weight on the neck. I believe this would be superior protection especially for the neck. In low threat areas the outer shell could be left off for comfort! Other improvements are possible! Also, helmets are used for other things such as a (steel pot anyway) a vessel to heat water in, a improvised digging tool, a not-too-comfortable seat. etc.
great video!
Steel seemed to have been the best choice at the time, taking into account that the army was only thinking about blunt force at the time and not all the scientific implications of aerodynamics a bullet or high speed projectiles have, like shrapnel, and that Kevlar was a lot better for that, since it has many layers that the projectile has to go through, and that steel has only one, but they didn't realize that until the '70s. This is why the steel helmet performed better on this test.

@@theisFandy the main purpose of the steel helmet was to protect you from falling debris from artillery while in a trench, against direct fire you would strap on the additional M16 Stirnpanzer plate
@@TrueFork true. But another purpose was to reduce the death from bullets. Yes, the helmet could help you to survive even shot (from specific angle). There was interesting story from I ww. I believe British army considered to come back to the leather hats or whatever they been called as there was more injuries than before. But they didn't took into consideration that more injured was equall to less dead. Because of that they stayed and steel became the standard in the next wirld war. Why there was no cevlar helmets? Fkn technology gap. Simple.
You are wrong. The aerodynamic were very well known even in 20s. The problem was the lack of technology. That's why there was no cevlar/bulletproof jackets among the masses of soldiers during II WORLD war. There was no mass production cost effective technology. The aerodynamics of bullets and the rest was extremely well known, especially when tanks were improved in the 30s. The steel helmets were the only solution as we're relatively cost effective and possible to mass production. At certain angle the bullet would ricochet from the helmet possibly leaving you just with light wound.
@@theisFandy El gringo te cuenta que los cascos de esos años eran toscos y no pensados con los conocimientos físicos actuales de aerodinámica, transferencia de energía y todas esas weas, por lo que los cascos eran ultra pesados y no necesariamente más efectivos que los modernos.
The helmets aren't designed to protect your head from being driven over by a tank. Their ability to protect against shrapnel or glancing bullets isn't going to be measured by a press. From what I've heard the biggest drawback of the kevlar helmet is you can't use it to cook soup in your foxhole.

All hits went through like a hot knife through butter.

The "worker helmet" is funny, because hard hats are meant to redirect damage. That's why they fall off your head so easily. If they just stopped falling objects dead, the force would go to the wearer's necks.
that is actually something I didn’t know and some interesting thing I got to learn today ! Well thanks!!
Not true. If something heavy were to hit your head and your hard hat was on tight, your head would be pushed and the object would land on your shoulders or barely miss you. While yes they redirect damage, they aren’t made to fall off. That’s why good quality hard hats are adjustable to fit tightly on your head. They also protect your head from hitting things yourself, like a low beam or ceiling and stop projectiles like blades or fragments. For example, lay a hard hat down and try to hit it with a hammer. The hat will just keep moving, like your head would if you had the hard had on tight, as you should

It's clear that the kevlar soldier helmet is designed to absorb impact energy by deformation.
The steel helmet took 10 tonnes, and that's far more than any neck or skull can take, and only the harness inside that helmet absorbs energy from an impact, while with the newer helmet the harness and the shell both absorb energy.

@@spicydiarrhea5662 They were hardly just a decoration/morale booster, they were designed to protect against shrapnel mainly from artillery and grenades, and they did that well.

I wasn’t aware of the ‘ hydraulic press ‘ threat to civilisation. Thanks for the heads up
Great background music
Though the Kevlar would appear to give you less protection, it's actually better protection as it will dampen the blow you received. While the steel one will be far better at transferring the energy to the wearer.
Also, I suspect the weight they hold is very different, making for a striking difference in comfort after prolonged wear. Which might not mean much, but when you're a soldier that has to wear it all day for days at a time, it's all the difference it takes for your own body to resist longer in harsh conditions.
It’s like with old vs. new cars. Old steel carosseries will shine like a star after a crash while new cars will be crumpled up to high hell, but what we forget that inside the shiny steel box _you’d_ be crumpled up to high hell.
When being attacked by a hydraulic press, does dampening the blow matter at all? :P

Kevlar is meant to be more for shock absorption, like the vest it's meant to divert kinetic energy from a bullet to be at a non lethal speed. Meanwhile a steel helmet is not shock absorbing, but because it is solid steel it will deflect any kind of projectile, however the shock and the kinetic energy will remain, so you can possibly have a concussion but at least you won't have a hole in your head.
Was gonna comment something similar but you beat me to it

I am glad to hear that you were wearing your helmet for that incident! That would not have ended well without one 😬😬
"The construction helmet is ideally created for my purposes, I experienced it on my head, when a 6-meter rack of clamping scaffolding did not just fall on my head, but as if someone swung it with a sword. I thought I would cut it lengthwise into two parts. It cleared so that the whole construction site probably heard. But the helmet withstood the blow with honor.
The old army, for its time and its war, was normal,
A modern helmet designed for its tasks in modern wars.
A police helmet is not built to resist bullets unless it is a sphere.
This helmet absorbs shocks like a construction helmet, but with improved plastic, improved shock absorption belt liner and all-round head protection. Everything you need to disperse the demonstrators.
So HELMETS ARE EVERYTHING, HELMETS ARE ANY IMPORTANT.
I think that the purpose of this video is not to prove anything to us. And just to show that helmets and helmets were invented for a reason."

Kevlar helmet at the press: if I go down , you go down with me.
ah yes for the very common event where you have your head crushed slowly with a hydraulic press
Even when the breaking point is much higher at the steel helmet, i consider the kelvar one as the better protection against real threats because of the Absorption features and layered build.

nah it's trash lmao
"Do not try this at home" is a great warning because casually most people have an hidraulic press at their homes.
yep, i have a lot of helmets too
@@unfamousk4y what the? for what u keeping that in ur house
he is sarcastic
@@marloplayztsbthespaceboy1807 Really????? No way, you're kidding!!!!!!!!
LOL I did have a 100 ton hydraulic press at my parents for splitting stone!
Well, I guess the main lesson that I've learned from this video is that: "The past is unbreakable"
Can’t wait to try this at home
This reminds me of a semi-related fun fact. I wanna say it was the British army, but it was found that shortly after switching from leather helmets to metal ones, the number and rate of head injuries from combat dramatically increased. It seems counterintuitive, but this was actually a good thing since those with leather helmets rarely suffered head injuries as fatalities were not categorized as injuries.
That would be the german army. Their Pickelhaube (spiked helm) was made of leather.
@@python27au Nice. Another fun fact!

Fun fact: roller blade wrist guards have a plastic insert that stops the wrist from bending too much during a FOOSH (falling on outstretched hand) injury - the most common fall for beginners. When they first started making the wrist guards, people would complain that the plastic insert broke when they fell over. A few companies switched to metal inserts. Then the companies found that people's wrists were breaking because the metal wouldn't break and absorb any of the force. So they went back to plastic.
This is surprisingly satisfying.
Agreed
First time ?

i new it just like everthing else, things from back in the day are made much much better
Are we just gonna ignore the fact that dude got a random WW2 army helmet a 2008 army helmet and a police helmet casually liying around in his house?!
do... do you even know when World War 2 was? (also yes we are going to ignore that because you can obviously get all those things online. god.)

Ww2 helemets were mostly against low impact fragments, low speed bullets, and basic "don't hit your head on stuff". They were cheap, easy and fast to produce in big quantities and we're more useful than not. They would deflect bullets and fragments but if pierced (if that surface was broken) you would be injured or dead.
Modern ones can deflect but are able to absorb the impact, they would contain the bullet or fragments and some of the kinetic energy, although you would feel like getting hit in a head by Mike Tyson at least your would live. Biggest difference would be at around 90deges of impact(less likely to deflect)

Helmet 1968 And the second world war ended in 1945.
It's kinda like classic cars and modern cars. Classic cars had big solid steel frames and bumpers, that at low speeds, you'd deflect most things, but high speed crashes are lethal. Modern cars have plastic bumpers, built to crumple and absorb kinetic energy.
Don't know why they even bothered with helmets for low speed bullets. Too lazy to dodge?
@@brendankelly2653 does modern cars hace less chances of death?
I'd like to see how the helmets hold up to different caliber rounds, the hydraulic 'squash' was fun to watch but no one runs into a hulk smash wearing them! 🤣
the hydrolic press only proves the kevlar it is better since instead of pulling appart and ripping under high presure it crumpled and stayed intact meaning there is a good chance that instead of ripping appart after getting hit by a bullet or letting one through it would rather catch it and transfer all of the kenetic energy to the helmet
@@uncool9731 Well and in a war everybody gets hit by only one bullet. Great, then why are still some dying? After this, the second one is "free to go", so I guess, don't even start one, but humanity will never get smarter.

*OMG! I love teh SSh-68 helmet!*
imagine fighting for your country but years later your helmet was crushed with a hydraulic press by some random dude on a website
no no hes got a point
Everyone: helmets are meant for projectiles, not being crushed
Me: haha helmet pancake
The bots detected your virginity.
Literally those old helmets are even better than a helmet of the present😮
When are you gaguing the damage from - I assumed it was from when it first split but the kevlar one did ages before the measure was taken
Армейский шлем сделан на защиту от проникновения пули и осколков, доля секундных. А не под прессом сжимать, шея не железная
Да но когда человек падает под чтото и зжатие такое крепкое спосает солдата.
@@Matroschin ну,а теперь представь насколько мал шанс что на солдата будут действовать сжимающие силы против попадания в каску пули/осколка??🤷♂️
@Кто Там 🤦♂️🤦♂️🤦♂️ этот комментарий предоставил доказательства что вы плохо учили физику в школе и не разбираетесь в теме и материалах.
Кевларовая каска держит пулю по нормали,стальная каска в нормали пулю не вывезет,а вывезет только по касательной траектории.
