摘　　要：对平面变形的正反向挤压问题建立运动许可的连续速度场并获得上界解析解。该解与以三角形速度场得到的上界解和 Avitzur 以柱坐标系连续速度场得到的上界解进行比较表明,本文解法有时可得到更低的上界值,且可得到通解。A kinematically admissible continuous velocity field is established and applied to the plane strain in reversible extrusion. An upper-bound analytical solution is thus obtained. In comparison with those solutions as obtained from a triangular velocity field and Avitzur's continuous velocity field in a circular cylindrical coordinate.sometimes the solution will give lower values even a general solution is available.
