Abstract
A hybrid experimental-numerical approach is employed to characterize the plasticity and fracture properties of 1.0 mm thick aluminum 6061-T4 sheets. The experimental program consists of various tests corresponding to different stress states ranging from simple shear up to plane strain tension. The anisotropic elasto-plastic behavior is characterized by a modified Barlat89 model (MAT36E) in the commercial finite element solver LS-DYNA. The stress state dependent ductile fracture behavior is modeled with the Xue-Wierzbicki fracture criteria, which is implemented into the phenomenological damage model GISSMO in LS-DYNA. A deep drawing experiment is performed for the validation of the material card. The FE-simulation of the deep drawing experiment using the calibrated material card is able to predict the onset of fracture accurately.
