Advanced material models from the Chaboche family are well suited to cover springback effects and strain rate sensitivity in sheet metal forming simulations. Experimental techniques (such as tension-compression tests and other tests), parameter identification, and applications to real parts will be presented together with first steps towards virtual materials testing by means of texture simulations. Materials ivestigated range from different mild and high strength steels to magnesium sheet tested at elevated temperatures.
