Title: Автоволновая модель упругопластического перехода в деформируемой среде
Abstract: The conditions for the generation of autowaves of localized plasticity during the elastic-plastic transition in solids are considered. The similarity and difference between the deformation processes according to the Lüders and Portevin–Le Chatelier mechanisms are analyzed and an explanation of these regularities is proposed, based on the introduction of concepts of active deformable media capable of generating switching autowaves and excitation autowaves. The conditions for the formation of such autowaves and the quantitative characteristics of the processes responsible for the transition to plastic deformation are considered. The relationship between the autowave characteristics and the rate of stretching during mechanical tests has been elucidated.
