Hello,

I wish to know if it is possible to use a non-linear plasticity model in Abaqus with separate loading and unloading material characterization due to hysteresis. This question is usually confused with Mullin's effects in rubber which i hyper-elastic or visco-elastic which experiences no plastic strains until damage even at large deformations which comes back to zero stain upon load release. Instead some hyper-elastic-plastic or non-linear visco-elastic plastic or visco-plastic correlation until material stabilization for 3D solid elements that can be used for a non-linear geometry. 

Can a combined isotropic-kinematic model be able to simulate this behavior for a thermo-mechanical simulation under fluctuations or a transient simulation?

I wish to work on creating such a material model tool/plug-in that can very effectively predict the behavior of the material in service. I would appreciate help in this regard. Thank you.
