This thesis focuses on the development of an automated bulge test procedure that can be used to measure and analyze the mechanical properties of thin films on polymer substrates. The system was specifically designed to evaluate material characteristics like residual stress, elastic modulus, and crack formation under equi-biaxial loading condition. One of the main materials tested was aluminum-coated Kapton, which is commonly used in flexible electronics, aerospace applications, and as electrical insulation. By automating the testing process, the system ensures consistent and accurate results for the evaluation of thin metal films on polymer substrates. The setup also allows for detailed investigation into how cracks form and propagate in thin films, offering valuable insights into material deformation and potential failure points. Ultimately, this system could be an tool for improving the mechanical properties of polymer-based materials, particularly in industries like electronics and aerospace.
