Hi!

I'm playing with plastic strain dependent on the stress level. I have problem, when stress level goes down at the same time plastic strain is going down.
So i have question for you. How to define plastic strain which will remain constant during unloading?

p.s. im using stationary solver

Thank you in advance!

Hi,

you can use "Perfectly plastic" in "Hardening model" in the Plasticity Model, so that you will not get hardening, and so without increase/decrease of yield stress. Did you mean this behaviour?
