Biaxial materials testing.

Continuously increasing recommendations to new products require optimized material applications. For this, new calculation and optimization procedures, as for instance the finite element method (FEM) are used. Such procedures allow prediction of the fabrication process and of the behaviour already during the design of a specific component. Examplified by high strength steel sheets the influence of the material during simulation of forming processes is highlighted within this contribution. Materials description and testing have directly been coupled. As a main topic regarding development of complex material models biaxial materials testing and the respective parameters are adressed.
