A SOLUTION OF SHAPE EXTRUSION OR DRAWING BASED ON DEFORMATION THEORY
（Department of Materials Science and Engineering; Central South University of Technology; Changsha 410083）
Abstract: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.
Key words: shape extrusion or drawing deformation theory upper bound approximation
