To elaborate and develop the theories of irreversible processes of deformation. Formulate and elaborate methods of solution of the principal and mixed problems of the theory of elasticity, plasticity, stability and destruction for homogeneous and partial-homogeneous bodies. Results. The model of plasticity deformation of materials with a plane of fluidity taking into account the changes of surfaces of fluidity during deformation is offered. Defining formulas of a variant of the theory of plasticity takings into account micro-deformations are constructed. The numerous problems of stability of elastic-plasticity bodies for a complex loading are investigated. Ii is shown that the history of a loading can significantly affect on critical parameters of constructions. The invariance of J-integral for a complex load is investigated. An algorithm of the description of after bifurcation behavior of elastic-plasticity bodies under a complex loading is developed. Product Description popup.authors popup.nrat_date 2020-04-03 Close
