Head Lebedyev Anatolij Oleksijovych, Registration Date 16-01-2001 Organization Institute for problems of strength NASci of Ukraine popup.description2 The influence of a kind of the stress state on the characteristics of strength and plasticity of investigated materials under low and high temperatures are investigated. The yield and strength criteria of investigated materials are established and experimentally verified. The constitutive equations of the theory of elasto-plasticity are formulated and experimentally checked up, which describes processes of simple and complex loading of materials of different classes, including anisotropic ones. The methods of the numerical solution of boundary value problems of the theory of plasticity with use of the developed models of elasto-plastic deformation are developed.
