analysis elasto-plastic

[ector]

hi guys, I have to model a plate with a central hole in plastic elasto regimen, until I worked in elastic regimen all ok, but now problems come.
the trend of the deformation voltage is:
e= 210000 mpa sigma snerv.=240 mpa elastic pattern;
ep=e/(100) plastic pattern.

As you can see, I have two broken, one for elasticity and one for plastic. the problem is that if I insert a new material with this trend, the simulation starts and freezes. How do I proceed? are always in almost static regime...:frown::frown:

I wonder if you can do this. . .

Thank you.

Hello ettore,

I can tell you for certain that swx simulation has no problem managing an elasto-plastic analysis with bilinear material.

At this point I have a question: but are you doing a "nonlinear" study to verify the behavior of the plastic plate?

Hi, swarzy.

Yes, yes, I changed a couple of settings and everything works. . .
