The use of light-weight materials, such as magnesium alloys, offers great potential for reducing pollutant emission. In addition, the complex material behaviour is to be modeled exactly in the design of sheet forming processes. In the scope of the work, the stress state-dependent material behaviour of the magnesium alloy AZ31B was investigated to improve the prediction accuracy of sheet metal forming processes. Besides material characterisation, the focus of the investigations was the development, verification and validation of a novel material model for the consideration of anisotropic hardening at a process temperature of 200 ° C. By including the anisotropic hardening behaviour in material modelling, the mapping accuracy of forming processes could be decisively improved.
