摘　　要：从弹塑性基本关系、流动关系准则及Ｈｏｏｋｅ定律出发，应用介质的动三轴、单轴和静水压实验规律，导出了物质的塑性势方程。对具体物质得到的塑性势Ｆ（σｉｊ，κ），在主应力和剪应力平面上为一闭合曲线，得到的本构关系表达式，对于砂土和玻璃钢两种介质进行计算。In this paper,the potential of plastic material is derived,which is based up on the flow criterion and the Hookes low,combined with the hydrodynamical triaxal compression test,the uniaxial compression test and the static test.We find the plastic potential F(σ ij ,κ) of the material which is a closed curve on the stress shear stress surface,and the calculated results are in good agreement with the experiment for the phenolic glass and sand.
