Abstract

An exact solution for the Drucker-Prager elastic-plastic equations with linear hardening and arbitrary degree of nonassociativity is presented. The accuracy of two approximate integration schemes, incremental tangent prediction with radial projection and one-step Euler (forward/backward) integration, is examined.
