dc.description.abstractA finite-element simulation of the shear cutting process is used to predict thegeometry of the cutting surface. A fully-coupled Lemaitre-type model is used in the process model for the description of the material behaviour. The extended Lemaitre model considers the influence of shear and compression-dominated stress states on the propagation of damage. Tensile tests with and without notches are used for the identification of material parameters. These methods are advantageous for the analysis of different blanking processes. Since damage parameters have a strong influence on the cutting surface quality, a numerical study isconducted to analyse their influence. The results of the simulations are compared with experimental data.
