Abstract
A self-excited wave model of plastic flow in crystalline solids is proposed. The experimental results pertaining to plastic flow in single crystals and polycrystals with different underlying mechanisms responsible for plastic deformation are summarized. The salient feature types of strain localization in the materials under consideration are captured and related to the respective steps on the deformation curves. The conditions at which the salient self-excited wave types of plastic deformation reveal themselves are determined. The applicability of the synergic self-organization approach to describing plastic deformation is substantiated. A self-excited wave model of plastic flow in materials with different underlying mechanisms of deformation is suggested.
