Residual Stress analysis of Equilateral Triangular Sectioned bar of Linear Work- Hardening Materials under Torsional Loading

Abstract

This paper deals with the residual stress analysis of of Triangular cross-sectioned bars of linear work-hardening materials under torsional loading. 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. © 2017 Elsevier Ltd.
