Stamping of Nonuniform Channels. 8. Strain State and Hardening of the Workpiece in Constrained Extrusion. 8.1. Plastic Zone under the Thick Wall

The determination of the strain state of a workpiece in constrained extrusion of unequal channels is considered for plane deformation with misalignment of the punch and matrix. Formulas are obtained for the coordinates of the points and the accumulated strain in the plastic deformation zone under th...

Summary:The determination of the strain state of a workpiece in constrained extrusion of unequal channels is considered for plane deformation with misalignment of the punch and matrix. Formulas are obtained for the coordinates of the points and the accumulated strain in the plastic deformation zone under the thick wall created.
