Stefan presents in his thesis an eﬀective and eﬃcient method to characterize the deformation and failure of sheet metals using DIC interpretation to avoid spending time doing inverse modeling. Based on the results of this method plasticity and fracture models can be calibrated for different elements lengths and used for advanced forming and component performance simulations. This method can reduce time and costs during the development processes of new materials and products.
