Alternating elastoplastic deformation cyclically hardening material

The paper considers the problem of describing cyclic elastoplastic deformation hardening material based on the equations of flow theory proposed by V V Novozhilov [5]. Determination of plastic properties of the material length of the current state of stress on translation of the yield surface, the maximum shear stress in the entire history of deformation and material hardening parameter, allowed us to obtain a description of elastoplastic deformation in asymmetric alternating cycles does not contradict the experimental studies.

Keywords: uprugoplasicheskoe deformation of the material, strength, yield surface, design diagram, loading cycle.
