Parameter Calculation in Constrained Extrusion of Unequal Channels without Hardening

Calculation of the technological parameters characterizing the constrained extrusion of unequal channels is considered, in the case of plane deformation, with misalignment of the punch and matrix. The limiting cases of asymmetric extrusion are presented: symmetric extrusion; and complete overlap of the small gap in the flow. The analytical expressions obtained permit determination of the total and specific deforming forces and the height of the walls that are formed.
