Final Report Abstract

Thermal plastic riveting is an established process for joining components of different materials. The technical process design and the design of the joint are primarily based on subjective experience and empirical tests on the (series) component. Computer-assisted process simulation is currently not state of the art. This research project closes the gap by developing numerical models for the heating and forming behavior of the thermal riveting processes hot forming and hot air riveting. To this end, numerical models were developed for real plastic riveting processes, taking into account realistic material and process conditions. The results of the numerical simulations show a high agreement with the experimental data and allow an estimation of the minimum heating times as well as approaches to evaluate the resulting material morphology by simulation.
