Unified Strength Theory Based on the twin shear strength theory, a new strength theory is established by Yu in 1991 which considered the effects of intermediate principal stress and can be applied to a variety of different materials.
As for most of the metallic materials, the tensile strength is equal to the compressive strength.
Therefore, the material tension-compression strength ratio.

The controlling factor for the wear of steel is usually classified by steel grade and wear condition such as wear materials and an environment.
Both the cutting wear and the cracking wear mechanism are suitable for relatively hard materials.
Both the adhesive wear and the fatigue wear mechanism are suitable for relatively soft materials.
