The Stress and Strain Analysis of Cross Wedge Rolling of Asymmetric Shaft Parts

Cross wedge rolling of asymmetric shaft parts has a series of problems such as the difficulty of forming, and the rules of mental flow are not clear until now. Rigid plastic FE models of the asymmetric rolling and symmetric rolling were adopted to analyze the difference of the stress and strain fields of cross section and vertical section in the two rolling processes, which illuminated the rules of the stress and strain fields in the asymmetric rolling process. The research of the stress and strain fields in asymmetric rolling has positive significance for recognizing the forming characteristics and predicting deformation defects in asymmetric rolling process.
