Résumé

Understanding and modeling of ductile damage mechanisms remains a major issue for many industrial cold forming processes. The ability of numerical modeling to predict the ductile fracture is indeed crucial. However, this modeling is limited because of the complexity to take into account the influence of the complex loading paths (multi-axial and non-monotonic, nonproportional, shear effects, etc.) on damage mechanisms.
