Abstract
In this study, we investigated dynamic fracture toughness and crack propagation velocity of rocks by using Charpy impact test.<BR>The results of the experiments showed that crack propagation velocity of the rocks depends on impact energy applied to it, and Q (impact energy/crack propagation velocity) correlates with static strengths of the rocks. Also, the dynamic fracture toughness of the rocks, which is calculated from the dynamic fracture energy obtained by using Charpy impact test, was found to depend on the impact energy applied with it, and correlates with crack propagation velocity and static compression and tensile strengths of the rocks.
