Composite members have the beneficial qualities of both materials.
Through numerous tests on rock, the existence of the intermediate principal stress effect has now been well recognized as characteristics of the materials [4] [5].The unified strength theory proposed by YU takes into consideration the effect of all the stresses in the characteristics line field[6], which can reflect the effects of the intermediate principle.
The theory is especially versatile in reflecting effect to different extents for different materials.
