Theory of Plasticity

The fundamental nature of material properties. Yield point phenomena. Brittle
fracture, toughness. Stress state at general material point, stress components
on a general plane, effective stress, octahedral normal and shear stress.
Strain and strain rate state. Small and large deformations. Mathematical theory
of plas-ticity. Constitutive equations - temperature and strain rate effects.
Yield criteria. Theory of strength, ref-erence normal and shear stresses.
Classical, invariant, mixed, general plain, combined and reference strength
criteria. Experiments and testing machines. Examples.
