Composite laminates theory can be simplified from reducing 4 stiffness constants to 1, and 5 strength parameters to 1. Master material and master laminate can then be found. If material A is 20 percent stiffer or stronger than material B, it is the same for all laminates. If laminate A is 30 percent stiffer or stronger than laminate B, it is the same for all materials. Instead of testing multip...

How can the titan be repaired it was blown up you silly ass
My name is AL, I'm sell employed, I smoke weed and live in my Mom's basement. I also helped the electronics with MITx protoype course on edx.
Why keep trying to analyze a complete failure of poor engineering..The ahole should have known that it was maybe good for 2 dives.😂
It's like being buried alive with a stethoscope. Only a fool would design this mess. Avoid the Abyssopelagic zone, there be sea monsters!
There is a reason why it was non linear, it was the layers compressing whicht also applies sheer forces in that bespoke layerline. Thats why its non linear and at a shallower depth, because the layers allready compressed again, after that its up to linear again.
Well i guess that reason worked out well
@@truesoulghost2777 yeah, it the reason why it went boom. It worked out well in the sense that we got rid of a crazy person.
Useful algorithm suggestion =) . Sending to students.
Fuck salt
39:10
As far as i understand the interesting bit of the non linear load strains on the dive 80 is related to nig bang and the rubbing traces ntsb found. I think shat thry say is that the boundaries between layers 1 to 2 (glued to 3) and also 3 to 4(glued to 5) became partly undone, which is seen at that point, and then went the pressure gpt high enough at further depth this became linear again because it was compressed enough (rubbing in the process). To be clear this is just from listening to all the hearings and reading many of the documents. Sadly thats only information, not knowledge, so i can have understood it wrong.
Se Picture of se Titan.....

They would have to spend some time in a decompression chamber before they could ascend back to the surface .
20 years US Navy Submarine Chief Petty Officer, 17 of those years underwater on a variety of submarines and even a submersible. Having said that, there was not enough tea in China or gold in the world to get me to go aboard that million dollar coffin Oceangate created. Unlike others, I blame EVERYONE who was part of this SCAM and the blood of the 4 passengers is on their hands. If they knew that this was a disaster waiting to happen as ALL of them testified at the Coast Guard investigation, why didn't anyone report this to the Coasties BEFORE it happened?
The monitoring system totally worked, they just ignored it. After the bang dive, the stress strain and noise profile by depth changed dramatically. Some channel went through the data, and it gave him two dives worth of warnings, he just kept moving the goal post, but he had said in one of his videos that if the sounds changed at the same depth, that would tell you it's failing. Then when it happened, he apparently ignored it or just didn't graph the data.
Someone needs to do a buckling failure study on five, one inch thick concentric carbon fiber wound tubes held together by one mm thick layers of resin (simulating the resin coating applied between cures). Or just put a one mm air gap between the one inch thick tubes. This will measurably reduce buckling strength particularly in resisting dome to dome compression. Since there are pre and post failure hull samples retained, it would also be instructive to run compressive strength test of coupons cut in circumferential and axial directions. Failure mode observed would help understand load transfer issues at interface with intermediate rings.
it doesn't matter... the underrated viewport was the key failure... that's why 2/3 of the POS's remains are in the rear.
@@SammyNeedsAnAlibi Not that the viewport retainer ring is missing and all its bolts are broke off. So it likely got pushed out the front. Probably by hull debris and oxygen cylinders as front titanium dome imploded rearward.
I think some company already did those tests, followed by thorough studies by NTSB and US and Canadian coast guards.
@@DrJuan-ev8lu That too is an excellent theory.
@@SammyNeedsAnAlibi clearly wasnt. It buckeled at the Interface rings, where the bigges sheerforces split the layers. That also replicates the implosion pattern.
Has the Titan been repaired? My family and I are eager to go see the Titanic!
A little superglue, and it should work just fine once again!
too soon, but very accurate!
If that is a joke, it is in very poor taste.
I guess narco sub manufacturers took notes and now make these to go deeper. You can do one run for them and they'll borrow you the sub to visit the Titanic.
@@carolcook6130how about captain Stockton Crunch?
Ah, so this is where "Dr. Ing" is at. 🙂. When i saw the title of this vid on my feed, I was going, "Oh no! Joe Pesci will be ranting and raving about people stealing his stuff over on his site" LOL But I know they (Ing/Pesci) have been in contact for awhile on this subject.
If you're talking about who I think, he has great engineering knowledge and thoughts, and I enjoy all his videos. But it does seem like he's a little more concerned about what other people are doing than I would have thought. In any case I respect his channel and his content. He's smart
@@ED-es2qv Someday, I might change his nickname from "Joe Pesci" to "Cat-Man" , but that is a reach.🙂 as Adam West has dibbed's on that real nick-name.
A killing machine by design !
also one of the rare problems that solved itself...
In all of these reports I have yet to hear how this composite section was cured. You mentioned an oven one time, that is the first time I heard this. I would think with a structure this thick that it should have been cured on the mandrel in a high pressure autoclave to eliminate porosity and voids. Of course, this probably wouldn't have prevented this disaster, but perhaps may have helped.
In various testimony and technical documents it is kinda common knowledge and is explained the hull was wound 1 inch at a time and cured in a autoclave on the mandrel.
AIUI where the hull was spun/wound was 1+ hour plus away from the curing oven at another factory/shop. They spun an 1" , took it to the oven, cured it, let it cool, then brought it back spun another inch then took it to the oven again , rinse repeat till it got to the final thickness. This process took many days- something like "2 weeks or more?" IIRC , to finish the hull tube , between spinning , moving, curing , cooling , moving , x6 times. It was loaded with voids and imperfections because of this.
@@chrisperrien7055 Yes, they also ground/sanded down the bumps in between layers which caused the ply's to be broken and not be continuous. In some places more than half the ply's in a layer were interrupted.
@@salland12for what it's worth, the picture looks like the 1" sections came apart as if they weren't attached to each other. Definitely didn't fail like a homogeneous material, whether that's good or bad I don't know. My unrelated experience is that layers of plywood make a great jack base that's extremely hard to break, yet when I use a thicker but single 2x6, it breaks under much less load than the plywood. I'm guessing it's bad when your submarine is layered, but I just don't know.
Iv seen people on here cure and take care of resin table tops more than this deathbox submarine

Verry intersting Webiner, i learnt a lot of things from you, i will contact you as soon as possible. many thanks for all the team
Thanks ❤
Prof. Tsai is 95 years old and is holding an intensive matrix lecture for an hour. With my full respect and admire, i wish you a longer and healthy life Professor.
Love this lecture - thank you for condensing heritage and current(ly developed) TPS into one video and briefly mentioning European developments on CMC TPS/Hot structures. The German Aerospace Center (DLR) was also a contractor for the X-38's C/SiC hot structure nose. A minor correction in your presentation is that Herakles, a Safran company, no longer exists, and the entity that developed the CMC hot structures for the IXV is now called ArianeGroup (a Safran-Airbus company).
Very informative

Thank you for placing the webinar on YT. I missed this one and finally got a chance to watch it. Another advantage of using YT is allowing comments. On this one, I have a couple questions that perhaps can be answered. If not...I'll try to better and get on these calls :) Composites on aircraft - In the passenger compartments - are most of the composites traditional plastics such as ABS? In my years involved with composites, plastics always had dramatically worse flame spread and smoke index characteristics than FR thermosetting resin based polymers like FR FRP. Because traditional plastics (such as ABS) tend to melt quickly, have there been advances to dramatically improve the fire/smoke ratings of these plastics? Li batteries - Wow! I had no idea of the massive scope of what is happening with the li battery. In recent years, the bat manufacturers have implemented safety circuits withing the battery enclosures to sense thermal runaway. Typically they sense each cell and then shut down either the discharge transistor(s) or the charging transistors (or both). This has helped a lot. Yet I am curious why the batteries burned, outside of physical abuse, for most of the incidents? Excellent presentations and thanks to all the speakers! Peter - FiberDesign
I missed this webinar and glad you can put them up to look at later. This was an excellent presentation. I look forward to more of these webinars....Best Rgs....Peter
