Kurzfassung
The aim of this paper is to investigate the properties of a specific implicit gradient-enhanced damagemodel which is coupled to elastoplastic material behavior. The model may be regarded as a direct ‘nonlocal’extension of the classical ‘local’ Lemaitre-type damage-plasticity formulation. A simple benchmark test conductedin the numerical part of the work reveals that the discussed model is capable to suitably counteract the undesiredmesh-sensitivity effect typically observed in finite element simulations involving material softening behavior.
