摘要：

The present paper describes the resolution of the numerical simulation of the sheet cutting problem by the large time increment method in the version applicable to non linear problems in large displacements with contact and friction. To modelize elastoplasticity and damage, we use the prandt-Reuss behaviour law and a new stable damage model standard generalized to metal forming in its exension to the non linear geometrical case.
