| Abstract |
The plane model of a plastic body is used for studying changes in the elastic properties of elastoplastic bodies subjected to plastic deformation. These changes are due to the formation of defects in the slip systems. Expressions for the rigidity matrix of an elastoplastic
material with defects are obtained. The anisotropy of elastic properties due to directional formation of micro-defects in the slip systems is established. The experimental results obtained for steel samples by measuring the elastic modulus during unloading, with the use of destruction diagrams, are presented. These results show qualitative agreement between the theoretical and experimental data. |
