Abstract

Abstract: In this work, an elastoplastic material model coupled to nonlocal damage is discussed which is based on an implicit gradient‐enhanced approach. Combined nonlinear isotropic and kinematic hardening as well as continuum damage of Lemaitre‐type are considered. The model is a direct nonlocal extension of a corresponding local model which was presented earlier (see e. g. [1], [2], [3]). Conclusions drawn from a numerical benchmark test performed in this study demonstrate that the nonlocal damage model is suitable to provide mesh‐independent solutions in finite element simulations.
