The model uses the classical Mohr-Coloumb yield criterion: a straight line in the meridional plane and an irregular hexagonal section in the deviatoric plane. Field variable columns appear in the Data table. The hardening is assumed to be linear for illustration purposes. This model is a particular type of Mises plasticity that includes analytical forms of the hardening law and rate dependence. Stress, , in the elastic-viscous network.
