Abstract

In order to accurately predict damage and failure evolution in metal forming processes such as stamping, blanking and bending, a finite element model has been developed which is valid for the numerical description of such processes. Numerical simulation of the damage evolution has been modelled by means of a continuum damage approach. The Lemaitre damage model which takes into account the influence of triaxiality has been implemented using the ABAQUS/Standard code. The model enables damage and fracture initiation to be examined under several different loading conditions and geometry configurations. An example of the L-bending process is given to illustrate the potential applicability of the model.
