How does COMSOL use the incremental theory of plasticity?

Please login with a confirmed email address before reporting spam

Hello everyone,

I am new to COMSOL, and I have a simple question on how COMSOL use the incremental theory of plasticity.


Incremental theory of plasticity will need derivative of yield function on stress components (i.e. d(ep)=d(lambda)*[d(f)/d(sigma)]

How does the previous calculation execute in COMSOL ? or where can I find the comments on this in all of those manuals ?

Thanks a lot !
