摘　　要：根据“可压缩连续体”的假设 ,应用连续体塑性力学推证出了多孔材料平面应变滑移线速度方程 ,并讨论了速度间断问题 。According to the hypothesis of compressible continuous body, the velocity equations of slip line on plane strain for porous materials are derived by using plastic mechanics of continuous body, and its velocity discontinuity is also discussed to investigate the regulation of the plastic deformation and the density of compressible material.
