Abstract
In this work an aluminum sheet was characterized under static and crash relevant loading conditions. Tension, biaxial and shear tests were performed. The parameters of isotropic and anisotropic material models in combination with a failure model were determined through the simulation of the different tests. The applicability of the used material models was verified by comparing experimental and calculated results of fracture mechanics tests, namely Kahn-specimen tests.
