Abstract：

Because of the nonuniform plastic deformation,residual stresses occur in spun parts. The magnitude and distribution of residual stresses have an important influence on used property of spun parts.In this paper,residual stresses of spun parts have been estimated by elasto- plastic FEM. The influence of the process parameters( reduction in thickness,feed,roller angle,blank thickness, material properties,etc.) on the residual stress distribution has been obtained.The calculated results are compared favourably with experimental results.
