In this paper a coupled elasto-plastic and damage model is presented and applied to predict the ductile damage accumulation under non-proportional loading conditions. The ductile damage constitutive equations, within the framework of the continuum damage mechanics, were coupled with the unconventional plasticity model Extended Subloading Surface1) in order to investigate the degradation of the mechanical performance of metals under the development of plastic deformation. Moreover, the tangential inelastic contribution2) was introduced to simulate the acceleration of the damage evolution observed during experiments carried out under non-proportional loading paths.
