In the context of metals:Isotropic hardening can be used for large-strain analyses of metals (> 5-10% true strain). Isotropic hardening is not meant for cyclic loading applications because it does not account for the Bauschinger effect. Moreover, applicability of isotropic hardening for non-proportional loading is left up to the user, although, generally speaking, it is meant for proportional loading only.On the other hand, kinematic hardening is usually meant for non-proportional, cyclic loading since the Bauschinger effect is approximated with this model. However, it is generally meant for small-strain applications.I think John provided you some guidance here: Entering non-linearity for Molded Pulp Product material (non-linear) (ansys.com)Regards,Ashish Khemka
