The default *MAT_PLASTIC_KINEMATIC is just a bi-linear plastic material model with isotropic and kinematic hardening. Please see these links for additional details: http://www.lstc.com/dynamat/pdfs/mat_003_theory.pdf https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v195/exd_ag/exd_ag_lsd_mat_plast.html For using multi-linear plasticity models one would need to use a command snippet just under the part, *MAT_VISCOPLASTIC_MIXED_HARDENING (or *MAT_225) and define a separate command snippet for the *DEFINE_TABLE or *DEFINE_CURVE (under Workbench LS-DYNA). Please note that the parameter ‘BETA’ controls the type of hardening behavior used. Kinematic (BETA=0.0), Isotropic (BETA=1.0), or a combination of kinematic and isotropic hardening (0.02061079.zip
