摘要 ASOLUTIONOFSHAPEEXTRUSIONORDRAWINGBASEDONDEFORMATIONTHEORYYuanXi(DepartmentofMaterialsScienceandEngineering,CentralSouthUnive... A new method based on deformation theory for analysing shape extrusion or drawing was described. The processes of the extrusion or drawing of regular polygonal or rectangular sections from cylindrical billets were discussed. The calculated results have been compared with known data obtained from upper bound method and were found to be in good agreement.
