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.

Entry knowledge

Regular completion of the specialized courses in the field of engineering technology and in the metal-forming specializations.

Rules for evaluation and completion of the course

The oral exam is conducted by a debate following a written discourse. The main emphasis is on the understanding of the principles and applications of experimental methods in forming in scientific research.

Aims

The objective of the course is to make students of doctoral degree study programe with special experimental methods necessary when assessing the functional properties of forming tools and formability of materials in the area of manufacture and research. The significance and application of technical measuring and testing in the development of the metal-forming technologies are emphasized.
Students will be able to creatively participate in conducting and evaluating experiments required in the technological processes of metal-forming. They will be cognizant of the necessary measuring methods and equipment with automated outputs and evaluation using computer technology.
