Using the software system ABAQUS, modeling of the copper powder compaction process was performed with the relative initial porosity of 10 % in three variants of input friction conditions: without friction and friction coefficient was 0.2 and 0.4. The Garzon’s yield condition for plastically compressible continuum was applied. Regularities of the vector components displacement distribution, density, hydrostatic stress during porous material compacting in the container were identified. If the friction coefficient is 0.4, it will be revealed two strains hindered zones - under punch and on the punch periphery at the greatest distance from the active punch. Angles reversal principal strains were defined. Area of the largest rotation was revealed in the main deformation periphery region of the workpiece adjacent to the die surface. In this area, the minimum principal strain (compression) deploy at almost 45 degrees to the corresponding rotation of the maximum principal strains. The comparison of the known experimental data performed, and it show good qualitative convergence results.
