Dear all,

I am going to model the plastic properties of my material. The experimental stress-strain curve of the material shows strain hardening up to strain of almost 0.3 and then stress decline. Can you please inform me of the steps that I need to take for modelling this plastic behavior? I tried the Multilinear Isotropic hardening that do not allow to model this type of plastic properties.

Thank you.

Thank you.
My sample is a porous material that its mechanical properties change during uniaxial compressive loading from strain hardening to shear failure.
My question is how to model this type of plastic deformation in Ansys workbench?
