A new approach to calculating the strain after equal-channel angular pressing is proposed. It is based on the kinematics of material points traveling along physical mass-transfer trajectories. Formulas for determining the accumulated strain and its shear and rotation (torsion) components are derived. The strain component distribution is found as a function of the cross section of a workpiece and the angle of the channel intersection in a die is established. The calculation results are verified.
