Abstract
The development of elastic and plastic deformation in a crystal immediately upon termination of the stage of active loading has been computer-simulated by methods of molecular dynamics. Depending on the level of deformation reached at the active loading stage, the subsequent relaxation process may follow different scenarios. In particular, an interval of deformations is found for which the crystal lattice occurs in a state of unstable equilibrium, whereby small variations in the degree of compression may lead to significant changes in the character of formation of the bands of localization of atomic displacements. The obtained results may be important for an analysis of the influence of the inertial character of structural changes on the development of plastic deformation in crystals.
