Abstract

With the use of the variation condition for bifurcation of the process of deformation of an inelastic body, the conditions were studied under which a regular system of shear and compaction bands forms. It has been established that a regular system of bands where plastic deformations are localized should form, most likely, in materials with well-expressed ultimate yield. Internal friction and dilatancy promoting the development of instability of the material in the regime of strengthening contribute much to this phenomenon.
