We characterize the mechanical properties of joints and assess them in terms of their deformation and failure behavior. A particular focus of our work is joint modeling for crash simulations, as this is the only way to analyze such a large number of different joints in the whole vehicle structure, thousands of them, and predict their capacity. By simulating joining processes such as punch riveting we are able to determine the aspects of the process that influence the joint properties.
