Résumé

The purpose of this paper is the prediction of forming limits computed from an initial defect approach combined with a rate-independent polycrystalline plasticity model. The algorithm used for the integration of the material behaviour inside and outside the localization band is presented. Results are compared with the forming limit curves at necking and at failure for 6116-T4 aluminium.
