Course detail
Experimental Methods in Forming
FSI-9EMTAcad. year: 2023/2024
The course deals with the specialized methods of measuring and evaluating attendant phenomena in metal-forming. They include mechanical testing, qualitative and quantitative evaluation of measuring of metal-forming and ejecting forces, resistance to plastic strain, strain rates and temperature. The evaluation is dealt with from the viewpoint of individual methods of metal-forming and the operating conditions of the tool. Also discussed is the application of the methods of light and electron microscopy when assessing the morphology of the surface of tools and formed pieces.
