A Viscoplastic Algorithm for CAP75.
Abstract
A viscoplastic formulation based on Perzyna's elastic/viscoplastic 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)
