In order to reveal the evolution of ductile damage during plastic-working processes and to ensure the quality of the product, the formulation of a ductile-damage model has become an urgent need in plastic-working theory. In this paper, a ductile-damage model based on the precise measurement of relat
Sheet-metal forming simulations are made using a plane-stress yield function proposed by Ferron et al. for orthotropic sheets. Following the general method for the integration of rate-independent plasticity models, the yield function has been implemented in the implicit Abaqus=Standard ΓΏnite element
