• rolled sheets generally show an anisotropic behavior with respect to both plastic hardening and void nucleating particles. In the present contribution, the plasticity and rupture behavior of thin aluminum sheets is characterized by using smooth tensile specimens and Kahn specimens. Three-dimensional finite element simulations of ductile rupture of small specimens are performed using the Gurson-Tvergaard-Needleman model. As this approach does not appear suitable for modeling crack extension in large structures, a two-dimensional simulation using a cohesive zone model is adopted. Finally, the conditions for simulating slant fracture are addressed. Model modifications accounting for anisotropic behavior are applied in [4] but will not be considered here.
