Abstract
The present work presents the results of mathematical modeling of deformation and thermal processes of compaction of viscous compressible materials. An analytical solution of the problem of one-sided compression and extrusion of powder materials is found which enables us to establish different regimes of compaction and extrusion and to find criterial conditions for their realization at a qualitative level. The numerical analysis of the influence of the nonunifomity of the thermal regime and the conditions of heat transfer on the regularities of compaction nd extrusion of the materials is performed. It is shown how the models developed facilitate the solution of practical problems of producing the concrete items.
