摘要

Sliding crack model is employed to simulate the strength of rock material under dynamic triaxial compressive loads. Stress intensity factor of crack array considered is estimated by pseudo-traction method. A dynamic crack growth criterion is used in the analysis. The simulated strengths of a granite obtained by the sliding crack model agree with the experimental resu1ts.
