摘　　要：过一点的不同平面上的正应力随着平面法向的变化而改变。本文首次给出了一点的应力全量及其应力偏量中的正应力变化的三维图形 。The normal stress varies on different plane at one point.The figures of normal stress at one point and the corresponding deviator stress are given for the first time in this paper.The relationship between the normal stress figures and the deformation types is analyzed as well.

关 键 词：正应力 偏应力 静水应力 正应力图形 变形类型
