Abstract
Abstract
A method is proposed for producing a significant reduction in the magnitude of the residual stress generated after cold drawing of a bar. It consists basically of a skin pass at the final stage of drawing and has a good levelling effect on the residual stress distribution as long as the final reduction falls within a specific range. The method was first proposed as a result of elastic-plastic finite element analyses using the ELFEN code developed by Rockfield Software Limited at the University of Wales, Swansea. The validity of the proposed method was verified by measuring the residual stress using the Sachs method.
