| Abstract: | A new analytical method on the upper bound theory and concept of extrusion center for non-symmetric extrusion is put forth. By this method,it can simulate the admissible velocity field and strain rate field. The influence of friction factor and area reduction on relative stress and optimal die dimension, die surface and optimum working process is given. |
