ABSTRACT
The literature data discussed in Chapter 1 convince us that the main regularity of the plastic flow process is its tendency to a non-uniform distribution of deformation over the volume of a deformable body, that is, to localization of plastic deformation, which manifests itself at all stages of the process. For this reason, it seems that sufficiently complete information about the laws of localization processes can serve as the key to solving the problem of plastic flow. It is also clear that the success of an experimental study of the problem of localization is determined first of all by the availability of a sensitive technique, which makes it possible to observe the spatial—temporal characteristics of the deformation field in real time (in situ).
