Finite element analysis of a tailored blanks stamping process

This paper describes the computer simulation methodology for applying the method of finite elements in the sheet stamping of a new type of sheet. Simulation of the cup stamping process by a punch of square section has been chosen for testing. The modelling of such a stamping process was carried out using a complete thermomechanical analysis including the modelling of the sheet welding process and the modelling of the stamping process. It has been assumed that the criteria for evaluating the quality of the theoretical solution is the displacement of welding line after stamping. The stress after the welding process and the deformation are essential for further stage of the stamping process.
