Bachelor thesis or Master thesis
There are various joining processes in plastics technology for joining complex assemblies together. Thermoset direct fittings offer significant advantages here, as they are economical, can be automated and can be removed without leaving any residue. Prominent areas of application for direct fasteners include the automotive industry (attaching front aprons, fastening seats, etc.), the aviation industry and the electrical industry.

These different areas of application place different demands on the direct screw connection. In a previous project, design recommendations regarding the geometry were identified through process variations. The aim of the work is to validate these design recommendations by means of a simulation. The first step is to identify and develop a suitable replacement model. In order to implement meaningful parameters in the simulation, it is also necessary to characterize the defined thermoset materials with regard to their short-term strength. Finally, the design recommendations of the previous project are to be compared with the results achieved and ideally expanded.
Objective
The aim of the work is the simulation of thermoset direct screw connections. To this end, mechanical tests are carried out, parameter studies for various geometries are set up and model parameters are calibrated.
