| Abstract: | This paper shows us that it is beneficial to a further comprehension of and more familiarity with the third and fourth strength theory by calculating the octahedron shear stress directly by means of the calculation of the principal shear stress at 45?of octahedron in principal units, and by calculating the shape-changed strength to change the shape strength ratio, which enable us to distinguish the relationship among the three aspects more easily and directly. |

| Keywords: | principal unit principal shear stress face of octahedron shape-changed strength ratio |
