A viscoplastic formulation based on Perzynas elasticviscoplastic theory is developed for geological materials using the Sandler and Rubin CAP75 plasticity model. The numerical strategy employs a one parameter Crank-Nicolson time integration scheme which provides options for explicit and implicit algorithms. A computer program called VPDRVR exercises these algorithms for arbitrary states of stress or strain. Author
