Summary
The course introduces students to the basics of plasticity theory of initially isotropic materials. Phenomenological description of phenomena associated with irreversible deformations in conditions of normal, cryogenic and elevated temperatures. The subject also deals with the influence of the deformation rate on the material response and the problem of finite strains.
