对抛物线模拔矩形件三维变形问题设定了运动许可速度场：以变上限与曲面积分方法得到上界解析解
A three-dimensional kinematically admissible continuous velocity field bas been established for drawing rectangular workplace through a parabolic die. Then, applying the in tegral as a function of the upper limit and the curved surface integral, an upper bound analytical-solution of the dra wing stress has been obtained .
