Anisotropic damage coupled to plasticity: Modelling based on the effective configuration concept

A model framework for anisotropic damage, that is kinetically coupled to inelastic deformations, is outlined. Key ingredients are the concept of the effective undamaged configuration and the assumption of energy equivalence. The pertinent rate equations for the chosen internal variables are integrated using the standard fully implicit scheme, and the Jacobian matrix of the resulting non‐linear incremental constitutive problem is used to compute the algorithmic tangent stiffness in straightforward fashion. Numerical results showing the effect of deformation‐induced anisotropy conclude the paper
