[@nafnaf0]

This is excellent. It gets into the details of why to use the different models and goes so simply. Thank you good sir

[@nb920]

Thank you sir for explaining complex concept in a simple way

[@danielsantiagosoto9639]

i just understood what i wasnt able to do during ng the past 4 months!
thanks so much!

[@m2n037]

Hi Prithvi, it will be really useful if you organize the videos in playlists so that we can bookmark it and come back to it later.

[@solidmechanicsclassroom3224]

Mukunda, Thanks a lot for your suggestion.
Do you mean playlists like strength of materials, plasticity etc. ? .. Could you please detail out your suggestion ( basis of classification) . Thanks :)

[@m2n037]

Solid Mechanics Classroom Yes. You can classify according to your preference but every video should be part of a playlist. That way it is easier to bookmark. Basic solid mechanics, advanced solid mechanics, elasticity, plasticity etc

[@solidmechanicsclassroom3224]

I shall definitely do that, thanks very much :)

[@journey_with_shivina]

This video is so helpful.
Thank you so much.

[@narasimhachopparapu4534]

can you please make a video on how to interpret yield surface? it looks crazy. why is the shape tilted oval etc. frustrated with the mathematical equations wherever i try to understand yield surface. just please make a video on how to interpret the shape & how to use it. thank you :)

[@sambasivareddybobba7843]

what is effective plastic strain

[@solidmechanicsclassroom3224]

Including effective plastic strain ( most effective terms in solid mechanics) are obtained from some sort of energy equivalence. The goal is to convert a multidimensional quantity to a single dimension( or a scalar). In a crude sense, these scalar quantities are easy to deal with while making design decisions.
This could throw some light on effective quantities in general

Can you please show application part of the plasticity

[@Mech.Masters]

How does the graph understands that yielding has occurred in the material? What are the calculation behind it?

[@solidmechanicsclassroom3224]

Simplest yield surface description is either through Tresca or von Mises

[@gvbu-ne5lr]

Hi Prithivi, which text/reference books you follow? I read 5-6 textbooks on plasticity but did not find what you explained. I will be grateful to you if you can give textbook you followed. I want to learn in greater depth with clarity as you presented in this video. Thanks!

[@solidmechanicsclassroom3224]

You can look at the following resources :
1) Continuum mechanics and plasticity by Han-Chin Wu
2) Introduction to Computational Plasticity by FPE Dunne
3) ruclips.net/video/XO4FdwEwjG0/видео.html
I forgot where these exactly stemmed from , possibly from multiple sources : university lectures, web resources, texts and my own thoughts

[@benf7223]

Nice Explanation. Thank you.

[@VishnuprasadRanganatha]

why it is named as kinematic hardening?....
is it because the oval's origion shifts from one place to other place?

[@qwm1007]

yeap, sometimes it calls translational hardening

[@mountainlion105]

Respected Sir, Is plasticity flow rule is applicable for isotropic hardening only?? In other way is the derivation of flow rule is based on the assumption of isotropic hardening?? Sir, please suggest me....

[@saifaddeenal-manaseer6325]

There's a flow rule that include back stress (kinematic hardening parameter) it's the same as the flow rule but with (Sij -alpha) instead of Sij

[@solidmechanicsclassroom3224]

Please check this to understand a little bit more on flow rule and hardening ...

Thank you, very helpful, God bless you

[@msdesf]

Thanks a lot, great explanation.

[@p0m91]

Thanks for the clear explanation

[@narasimhachopparapu4534]

what an explanation...its excellent...great work

[@sambasivareddybobba7843]

sir ur much much better than nptel vedios

[@rubanramalingam3875]

Nice explanation.. Well understood..

[@Lilhobis]

Nice video!!

[@EddieVBlueIsland]

Nicely done

[@The_Creator_Naman]

excellent work

[@sambasivareddybobba7843]

sir please explain Johnson cook theory plasticity sir

[@Mech.Masters]

What is uniform yield surface expansion?

[@adsamgideon9465]

very useful. Thank you for the video

[@djouhairaboulo]

thank you very much

[@kashyappadiya1476]

Omg thank you soooo much

[@manojkumarp2076]

Thanks bro...

[@arundevm.g.4090]

nice

[@jayjanuary4357]

1,000 to 1 expansion ratio.

[@VahidAzami]

Your accent is awful. please work on it. I can't barely understand what you said.

[@younesirvani4611]

thank you so much.
