Abstract

Basic concepts of the autowave model of development of a localized plastic flow of solids of different natures are considered. It is shown that plastic deformation develops in a localized (at the macroscale level) way throughout the process. The form of the observed localization patterns is related to stages of strain hardening of the material. The patterns are projections of different modes of the localized plastic flow autowave on the observation surface. An elastoplastic strain invariant is introduced, which is considered as the main equation of the autowave plasticity model, and its physical nature is discussed.

自动波可塑性：原理和可能性

摘要

考虑了不同性质的固体局部塑性流发展的自动波模型的基本概念。结果表明，在整个过程中塑性变形以局部（宏观尺度）方式发展。观察到的定位图案的形式与材料的应变硬化阶段有关。这些图案是观察表面上局部塑性流自动波的不同模式的投影。介绍了一种弹塑性应变不变式，它被视为自波塑性模型的主要方程，并讨论了其物理性质。
