摘要
对双曲线模拉拨与挤压设定了运动许可速度场与应变速率场，用曲线积分与变上限积分求得摩擦功率与内部变形功率，从而对双曲线模平面变形拉拔挤压问题得到变形力的解析解．
The kinematically admissible velocity and strain rate fields for drawing andextrusion through a hyperbolic die are established in this paper.The curvilinearintegral and the integral as a function of the upper limit are used for obtainingfriction and deformation powers.An analytical solution of mean plane extrusionand drawing stresses is obtained for hyperbolic dies.
