Simulation of Crack Initiation and Propagation in Blanking of Sheet Metal

Numerical simulation of crack initiation and propagation in a blanking process of a steel sheet is done using rigid plastic finite element code developed by the authors. The modified Cockcroft and Latham expression is used as a ductile fracture criterion and is linked with the simulation. It is assu...
