一、引言 滑移线法是塑性力学中的基本解题方法之一,但对于目前已有的滑移线理论,严格地说,它只限于解刚塑性平面应变问题。虽然曾有人利用“完全塑性”假设条件对轴对称问题做了一些推广,但更多的问题仍不能由此法得到满意地解决。为此,本文通过建立具有实际物 I. INTRODUCTION The slip line method is one of the basic problem-solving methods in plastic mechanics. However, for the existing slip line theory, strictly speaking, it is limited to solving the rigid-plastic plane strain problem. Although some people have used the “complete plasticity” hypothesis to make some generalizations about the axisymmetric problem, more problems still cannot be solved satisfactorily by this method. For this reason, this paper establishes practical objects
