Based on substantial experimental data, the effects of loading rates on the strength, fracture toughness and fragmentation efficiency of rock materials are discussed in this paper.
本文以充分的实验结果为依据，讨论了加载率对岩石材料的强度、断裂韧度和破碎效果的影响。

But the damage and fracture of rock is closely related to each other. And the relationship between strength criterion parameters of rock and fracture toughness of fracture theory is particular.
