Conclusions
A complex mathematical model of plastic flow of compressible materials is described. The model is versatile and, in the authors' opinion, free from many of the drawbacks of earlier models [9–11]. In particular, it can readily be adapted to analysis of virtually any process of plastic working under conditions of axisymmetric deformation; it enables all mechanical and temperature boundary conditions to be exactly fulfilled in all parts of the boundary S of a plastic flow region; it can be used for studying nonsteady-state processes of plastic working of metals with seats of deformation of complex shape (e.g., axisymmetric forging); it makes it possible to introduce starting data and extract resultant information in a form convenient to the user (production engineer).
