Within the scope of this thesis a material characterization of steel and aluminum alloys, which are common in the automotive industry, was carried out to determine the hardening behavior, anisotropy, strain rate sensitivity and forming limit. In addition to standardized tests and evaluation methods, further developments and new approaches were used. The comparison of experimental and numerical results showed the need for extensive determination of material parameters with consideration of stress state and forming history. Hereby an accurate prediction of the feasibility of complex sheet metal parts can be ensured.
