Al~tract--Sheet forming is a localization procedure of deformation and damage. In this paper, we firstly give a complete set of constitutive equations for elastic-plasticity coupled with damage. Then, a new continuum damage mechanics based local criterion for ductile fracture, proposed by the author

In this paper a relationship between the critical crack tip opening displacement (CTOD) at crack initiation S,, and the stress triaxiality a,,,/6 is derived based on the damage mechanics criterion for ductile fracture, and a modified crack tip parameter 6: and a modified CTOD criterion are proposed.
