一、前言众所周知,滑移线法在求解变形力方面,是基于平面变形人手而导出的理论性较强的解题方法。它在分析和预扳平面变形的成形参数和变形起到了一定的作用,但实际生产上重要的平面应力问题已得到精确的滑移线解者尚少。而轴对称的挤压应力问题,其滑移线解更是无精度可言。尽管在近期的塑性理论文献中经常有提出可以用滑移线法求解轴对称成形参数,可是没能见到 First, the preamble As we all know, slip line method in the solution of deformation force, is based on the deformation of the manpower derived theoretical strong problem-solving methods. It plays a part in the analysis and deformation of the pre-plane deformation forming parameters and deformation, but the actual production of important plane stress problems have been accurate slip line solution is still less. The axisymmetric extrusion stress problems, the slip line solution is no accuracy at all. Although it has often been suggested in recent plastic theory literature that axisymmetric formation parameters can be solved using the slip line method,
