Forming simulation models and the associated material characterisation are important factors when representing the increasingly complex deep drawing operations. Especially in context of automotive components, the finite element analysis ensures producibility prior to pilot series and minimises the risk of wasting resources by predicting the material behaviour as accurately as possible, such as plastic, thermal and anisotropic behaviour. For the representation of the plastic material deformation during forming, material models like Barlat or Hill, representing the real material behaviour as precisely as possible, must be implemented in the simulation. For this purpose, the model needs to describe occurring effects of the material such as anisotropy or further effects.
