Popis: A solution obtained by the FEM is proposed to the problem on the nonsteady-state extrusion of a cylindrical porous blank through a conical die and on the extrustion of a porous and a bimetallic blank of varying cross sections through a conical die. Zones of large and small strains are determined from the distribution of porosity. An analysis is made by the FEM of the stressed-strained state in the double-ended densification of porous blanks in rigid cylindrical dies. Cases of the densification of porous bimetallic blanks are also considered.
