Abstract

A vast amount of research continues to go into developing robust numerics to handle rate-independent crystal plasticity - either by making use of additional constitutive models or complex numerics. The present work attempts to circumvent such special measures by taking a new approach to develop a numerical solution procedure for a rate-independent crystal plasticity, relying on the Fleck and Willis gradient plasticity theory. The adopted constitutive model reduces to that of conventional plasticity in the limit of zero length parameter and, thus, constitutes a tool that covers both branches of plasticity.
