Abstract

A hybrid experimental-numerical approach to characterize plasticity and ductile fracture properties of aluminum 6061-T4 sheet is presented. The anisotropic elasto-plastic behavior is characterized by a Barlat89 model and the ductile fracture behavior by a GISSMO model in combination with the Xue-Wierzbicki model. We discuss then the validation procedure and the results related to a deep-drawing case where the simulation is carried out in a commercial FE-solver LS-DYNA. The drawing depth at fracture, as an exemplary result, shows a very good agreement between simulation and experiment.
