Residual Stress analysis of Linear Work- Hardening Materials under Torsional Loading

Abstract

This paper deals with the springback problems of 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 after twisting the section beyond the elastic limit. © 2017 Elsevier Ltd.
