A variant of the autowave model for generating structural imperfections when initiating localized plastic flow of crystalline bodies in a complex stress state is considered, based on the methods of the structural and analytical theory of strength and the principles of synergetics of the elastoplastic deformation process. The formulated model takes into account the development of processes at two interrelated scale and structural levels, allows us to predict the features of elastoplastic deformation of crystalline materials with complex loading trajectories in stress space and arbitrary stress change programs over time, takes into account the effects of localization and relaxation of energy in structural concentrators on the processes of self-oscillation of zones of structural concentrators during elastoplastic deformation.
