Numerical and Experimental Failure Analysis of Deep Drawing with Additional Force Transmission

Abstract: Deep drawing is a common forming method, where a sheet metal blank is drawn into a forming die by a punch. In previous research, conventional deep drawing was extended by the introduction of an additional force in the bottom of the cup. The force transmission initiates a pressure superposition in critical areas resulting in a delayed crack initiation. For numerical investigation of the considered process, an accurate modelling of the material failure is essential. Therefore, the parameters of the modified Mohr-Coulomb criterion were identified for the two high-strength steels HX340LAD and HCT600X by means of tensile tests with butterfly specimens. In this research, the fracture modelling is applied in the simulation of deep drawing with and without additional force transmission to enhance the failure prediction. The fracture criterion is validated by experimental deep drawing tests. Finally, the influence of the additional force on the prevailing stress state is evaluated.
