| Abstract: | A three-dimensional figure of normal stress and shear stress of one stress state was given, and the corresponding relationship of the figure with deformation type was analyzed. The figures can be divided into three main types, which refer to compression, plain strain, and tension, respectively. In addition, the stress-strain of typical points in simple tension, drawing, and extrusion was successfully analyzed by the figures. |

| Keywords: | normal stress shear stress Lode parameter deformation type |
