Summary

In this work two damage concepts i.e. the forming limit diagram and the micromechanical Gurson damage model [1, 2] were applied and compared by testing and modeling different specimens and components. Both concepts take into account the influence of the stress triaxiality on fracture processes. The forming limit diagram is considered as a phenomenological concept and does not account for the deformation history, while the Gurson damage model is based on the Region for bending tests Region for compression tests micromechanical description of fracture processes and describes the influence of the deformation history.
