The dependence of the circumferential shear strains of two different shear modes in a cylindrical coordinate system on the shear planes during a torsion-based severe plastic deformation is investigated using strain displacement relationships. Contrasting trends in the circumferential shear strains (increasing epsilon(Z theta) and decreasing epsilon(r theta) with radial distance from the center in the axial plane torsion and radial plane torsion, respectively) are demonstrated, which are in good agreement with published results.
