14. Description of lectures
Notion of the plastic body. Plasticity conditions: Tresca - Saint-Venant, Mises. The elasto-plastic deformation theory: Hencky's equations. Plastic flow theory: Prandtl-Reuss equations. Various models of the plastic hardening. Basic equations of the theory of plasticity. Incremental forms of the material equations.
