© IKVTopic of the work:
Various joining processes are available in plastics technology to join complex assemblies. Thermoset direct fittings offer significant advantages as they are economical, can be automated and can be removed without leaving any residue. Typical areas of application include the automotive industry, aviation and the electrical industry. In a previous project, process and geometry variations were used to derive design recommendations for these systems, which are now to be simulated. Central aspects of the work are the identification of a suitable simulation strategy, the selection of a suitable material model and the implementation of parameter studies. The thermoset materials are mechanically characterized in order to implement meaningful simulation parameters. Finally, the design recommendations of the previous project are to be compared with the simulation results and expanded.
Objective:
