Anisotropic damage coupled to plasticity: Modelling based on the e ective con guration concept

A model framework for anisotropic damage, that is kinetically coupled to inelastic deformations, is outlined. Key ingredients are the concept of the e ective undamaged con guration 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 sti ness in straightforward fashion. Numerical results showing the e ect of deformation-induced anisotropy conclude the paper
