摘要：
A theoretical analysis of the springback of hollow rectangular cross-sectional bars of linear work-hardening materials under torsional loading has been carried out. By using the deformation theory of plasticity, a numerical scheme has been prepared which determines the elasto-plastic boundary in addition to springback in the bars. Finally, an analytical generalised expression relating the angle of twist and twisting moment and residual angle of twist per unit length for bars under plastic torsion is obtained.
