Simulation approach to understanding materials in contact

Generative design techniques offer a promising approach to improve product development to meet specific needs more efficiently. This thesis explores advanced design methods for the enhanced development of electrical contacts. Additionally, techniques for obtaining real data to validate the methods being explored are provided.<br /> The focus is on developing a novel model to accurately simulate the contact area resulting from elastic-plastic deformation on electrical contacts. After successful validation of the model with real data, the contact resistance based on the simulated contact areas is computed to predict the electrical performance. This enables targeted design improvements, such as reducing power loss, selecting appropriate materials, and optimizing geometry. Furthermore, the thesis aims to optimize insertion forces and the number of insertion cycles, which are also crucial factors that influence the dynamic performance of electrical contacts. Modeling the maximum insertion forces and the number of insertion cycles provides insights into handling and expected lifespan. This holistic approach enables the design of electrical contacts capable of withstanding varying operating conditions while maintaining electrical performance.<br /> The methodologies presented in this thesis extend beyond electrical contacts and offer insights applicable to various systems involving surface contact or friction. This contribution advances engineering design processes and product performance.
