Modelling of industrial hybrid bonding processes considering fluid-structure-interaction

The subject of the work presented is focused on self-pierce-riveting and clinching in combination with adhesive bonding. In the industrial process chain the rivets and clinch-points are set before the adhesive is cured. A FEA reference model is developed for the elementary mechanical joining processes. The model is then expanded to consider the displacement of the liquid adhesive, including associated internal pressures. Coupled fluid-structure simulations, which include the interaction of the solid matter influenced in the mechanical joining process and the fluid adhesive, are presented. In a last step a surrogate model for the multi-point hybrid joint is developed and applied to industry-relevant structures.
