ABSTRACT
The experimental data presented in Chapter 2 prove the validity of the opinion that when stretching the initially structurally homogeneous sample at a constant speed, its plastic deformation proceeds in a localized manner from the yield point to fracture. In this interval, which in plastic materials can reach tens of percent, the patterns of localized plastic flow are generated and evolve, that is, the space-time heterogeneity (structure) of the deformable material is formed and develops. According to Seeger and Frank [Seeger, Frank, 1987], inhomogeneous defect structures arising in deformable media should be considered as the result of spontaneous ordering of the deformable medium.
