Equations of the general theory of plasticity of crystals

Equations are formulated for the elastic-plastic strains of crystals experiencing an inelastic flow of crystallographic shears. Local invariant relationships, including creep and active plasticity, are constructed. To take account of the microstresses a method of effective field is used. All the relationships are derived in a tensor formulation with reliance on representations about the physical regularities of the development of deformation. The derived system of equations describes a broad class of problems of the physics and mechanics of plasticity of an almost unbounded degree of complexity
