Discussional problems of plasticity physics

The actual discussional problems of physics of plastic strain are reviewed in brief. These are the problems concerning the details of the bend mechanism of motion of dislocations in crystals with the high Payerls relief, the role of point defects, especially interstitial atoms, in mass transfer in crystals, microscopic mechanisms of plastic strain in the plastic zone at the crack peak, microscopic description of plastic deformation of polycrystallic materials under different loadings with correct accounting for the participation of the grain boundaries in formation of the polycrystal defect structure, synergetic effects in plastic strain
