There are needs for one-sided mechanical joining dissimilar materials in automotive industry because it is efficient to fasten dissimilar materials for manufacturing light-weight vehicles. The full car crash model applying the joining technology with solid elements leads to an impractical computational cost due to the complexity of the model. Thus, we develop a simplified model with shell elements of the joining technology, which is efficient enough to simulate a full car model. We analyze and optimize the parameters of the simplified model that determine the behavior of the joining technology. The developed model is validated with lap shear and cross tension tests.
