Hi,
I faced a problem to simulate my ABAQUS model. I should use hyperelastic model because of large deformation, in addition, I should use kinematic or combined hardening model for its plasticity. But, it seems it's not possible in ABAQUS. How should I solve this problem? I appreciate your guidance.
 
What kind of material do you want to model ? Hyperelasticity can use so called permanent set as an equivalent of metal plasticity.
 
Its material is a layer of plastic. Indeed, it needs to experience large deformation and yielding in tension and compression since at first I stretch it which make it yields. Then in unloading process, it will yield under compression. Isotropic plastic model is able to simulate this process, but it has a problem which is increasing the yield stress under compression, so I need to use another model to simulate it and solve isotropic hardening issue.
