Abstract
A self-excited wave model of plastic flow in crystalline solids is proposed. Experimental data on plastic
flow in single crystals and polycrystalline solids involving different mechanisms have been correlated. The main
types of strain localization in the materials investigated have been established and correlated with the respective
stages of plastic flow curves. The best observing conditions have been defined for the major types of autowaves
emerging by plastic deformation. The synergetic concepts of self-organization are shown to apply to description of
plastic deformation. Suggested is a self-excited wave model of plastic flow in materials with different mechanisms of
deformation.
