### Summary

The subject where first a brief summary of the physical fundamentals of plastic deformation, i.e. physical principles of plasticity, stress – plastic deformation, behavior of material under uniaxial load and then are explained by basic plasticity concepts, classical plasticity theory and ways of using plasticity conditions. At the lectures students are acquainted with the basic concepts necessary to formulate and solve the forming problems and with the basic methods how to solve such problems. In the exercises, the behavior of the material during plastic deformation is numerically modeled and basic forming operations are solved by the discussed methods of analysis. At the end of the course students should be able to apply the theory of plasticity to computational methods in forming.
