Hi everyone,
I'm working under WB 14.0.
i'd like to model isotropic hardening of a polymer material.
My first issue is that i'd like to simulate non-linear elastic behaviour in loading but unloading too while we are in the elastic domain.
Unfortunately the only way we found up to now is to use a multi-linear isotropic hardening, but we loose the non-linear elastic unloading.
Then we'd like to model recovery in another way than linear once the material has plasticized.
Please find enclosed a picture that will (i hope) explain what i'm looking for:
Thanks for your answers.
