Academic year 2024/2025
Supervisor: prof. Ing. Milan Forejt, CSc.  
Supervising institute: ÚST all courses guaranted by this institute
Teaching language: Czech or English
Aims of the course unit:

The aim of the course is to explain to doctoral students the method of theoretical analysis of metal forming processes based on the principles of the physical essence of plastic deformation, including the effect of important thermomechanical conditions and boundary conditions of metal forming.
The course provides doctoral students with the ability to make use of physical, mechanical and thermodynamic principles of plastic deformation in relation to the structural changes and their limit states while conducting research in the field of manufacturing technology, specifically metal forming.

Prerequisites:

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

Significance of plasticity theory in solving problems of metal forming. Application of plasticity theory in computation models of theory of metal forming. Analysis of analytical and experimental-analytical methods for calculating the resistance to deformation and deformation, with computer support. Boundary conditions of deformation in calculation models in interaction with metal forming tools. Study of the processes of simulating macroplastic deformation for concrete metal forming technologies under real thermomechanical conditions. Effect of the rate of deformation. Using the FEM when dimensioning metal forming tools.
