MKP modelování, zkoušení a ověřování průmyslových adheziv používaných v automobilních aplikacích

Abstract

This project was conducted as a research for TÜV SÜD s.r.o. The project was carried out within the frame of TÜV SÜD and Czech Technical University in Prague. The purpose of this report is to present it as a master thesis project at Czech Technical University in Prague. The report is based on the work done on industrial adhesive. The report gives in depth insight of the work done during the six months project. The project's objective is FEM modelling, testing and validation of industrial adhesive for automotive applications. The use of resin-based adhesive for joining is promising. They show a satisfying behavior and further research was needed under full test conditions. At first, the ASTM standard tests were chosen for the physical testing of the adhesive. Then, the finite element (FE) material model of the adhesive was made to better match it with the physical adhesive counterpart. Then, the physical tests were simulated on FEA software PAM-CRASH. The validation and tuning of FE model was done using the physical testing data collected from the ASTM tests and adjusting the key parameters. The report should enable the reader to understand the physical model, the finite element model of the adhesive, the types of validation tests and simulations done for the project. This will also help other aspiring researchers and students to take it to next step and tune the adhesive material model using different material types, and/or for different adhesives.
