Abstract

A new approach to the problem of the plastic flow of solid crystals is proposed. This approach is based on studying the macroscopic localization patterns of plastic deformation, which can be considered as different types of autowave processes of defect self-organization. An unambiguous correspondence between the localization patterns and stages of plastic flow in metals is established. A new model is proposed to describe the development of plastic flow localization. A change-over in the patterns of autowave processes of plastic flow evolution and a transition to fracture are attributed to the specific features of the interaction between information and dynamic subsystems.
