Numerical Analysis and Optimization of the Residual Stresses Distribution Induced by Cold Expansion Technique

Abstract. This paper presents a numerical investigation about the influence of mandrel shape on residual stresses induced by the cold expansion procedure. Thus, ball and tapered pin are used for cold expanding the plate. As, the entrance face presents the lowest residual stresses throughout the hole...
