Abstract

A survey of the research carried out at the Institute of the Physics of Strength and Materials Science of the Siberian branch of the Academy of Sciences of the USSR into strongly excited states in crystals in application to the problem of the physics of plasticity and strength of solids is presented. Consideration of the theory of the behavior of solids in the fields of strong external effects leads to the concept of strongly excited states in crystals which is based on the appearance of permitted structural states in the interstitial space and the possibility of regular disposition of atoms not only in the crystal lattice modes but also in the interstices. A combination of this approach with the concept of structural levels of the deformation of solids and the principle of local calibration invariance makes it possible to substantiate the generation of a vortical mechanical field in a solid undergoing deformation. This theory is experimentally confirmed. Recommendations are given on the formation of vortical damping structures to create high-strength and wear-resistant materials.
