Abstract
The difficulties of the analysis of the stressed–deformed state of compressible blank compared to the analysis of an incompressible one were explained. It was pointed out that the continual theory of plasticity of compressible materials is based on an analysis of representative volumes of material. The basic assumptions allowing the simplifying of the solution of tasks of deformation of compressible materials were formulated.
