In the last decade clinch joining has become established as a cost-effective alternative to spot welding. Its development was brought on by the ongoing trend towards lightweight structures especially in the automotive industry. Choosing the tool which gives the best performance for a newly developed structure is a time and cost consuming process based on the principle of experiment. Numerical simulation early on in the design phase can reduce these costs. The simulation of the clinching process and the subsequent experiments to determine their static strength are presented in this paper. It has been shown that simulation offers a flexible method to study the clinching process. For some of the considered clinch joints the outcome of simulations are in good agreement with experiments. Although the results for the Tog-L-Loc system are not so highly regarded, something which can be attributed to the lack of remeshing algorithm, trends are nevertheless very well predicted. In further research, therefore, emphasis will be placed on the implementation of an optimized adaptive remeshing algorithm. The results of experimenting for certain joints prove that their outcome is very well predicted.
