The model developed allows for the simulation of the following mechanical properties exhibited by porous brittle materials: (1) degradation of elastic moduli and softening of material strength due to damage accumulation; (2) inelastic deformation due to growth of micro-cracks and evolution of micro-pores, and its effect on material strength; (3) effect of pore-fluid pressure on material strength.
Actually, the materials are divided into two parts, damage evolution region and complete destroyed region.
This characteristic may be related to the material strength of granite.

Considering differentiation of rock formation, we must select matrix materials with proper wear resistance, which is an important way to improve penetration rate [3,4].
Since bit matrix and granite were both brittle materials, they produced small caved blocks easily in friction and wear process, which generated occlusion in the interface.
