WebJan 5, 2024 · A non-local gradient-enhanced damage-plasticity formulation is proposed, which prevents the loss of well-posedness of the governing field equations in the post-critical damage regime. The non-locality of the formulation then manifests itself in terms of a non-local free energy contribution that penalizes the occurrence of damage gradients. WebIn Grassl and Jirásek (2006), the main framework of the present damage plasticity model was developed, which was called CDPM. In this work an effective stress based plasticity model was combined with a scalar damage approach with one damage variable for both tension and compression. The effective plasticity part was designed to describe the ...
