A general dynamically permissible velocity field for plane flow is setup in the paper. The force and energy parameters for extrusion (or drawing) are analyzed, and the optimum draw Angle is obtained.
本文建立了平面流动较为一般化的动可容速度场,分析了平面挤压(拉拔)的力能参数,获得了最佳凹模锥角。

Furthermore, we should setup the more elastic exchange rate system, considering exterior condition enough, avoiding "extrusion effects".
