Simulation of metal forming is of great importance for the automotive industry and their suppliers. The implementation of lightweight constructions is difficult because the springback behaviour of high-strength steels and aluminum is different from the springback behaviour of conventional steels. Design and production of forming tools for new lightweight materials has still to rely on "trial-and-error", which is very time consuming and costly. This is mainly due to the lack of efficient and reliable simulation tools for the modelling of springback.

New simulation tools and experimental techniques developed at IWM/SimBAU bring significant improvements in the numerical prediction of the sprinback effect.

• Advanced constitutive models with consideration of the Bauschinger effect


• Elimination of the numerical artefact of apparent stress relaxation


• Advanced damage models for a better description of the forming limits


• Determination of material parameters
