Summary:This paper deals with the analytical solution of the torsional springback problems of bars of elliptical cross-section of linear work-hardening materials. Using the deformation theory of plasticity, a numerical scheme based on the finite difference approximation has been proposed. The growth of the elastic-plastic boundary and the resulting stresses while loading, and the torsional springback and the residual stresses after unloading are calculated.
