It was confirmed through the experiments that dynamic fracture energy of rocks obtained from the general equation used in Charpy impact test contains lots of kinetic energy which is consumed as scattering of rock fragment after it has failed. Also, it was found that the dynamic fracture energy of the rocks depend on the impact energy applied to the rock specimens, and its increasing rate is supposed to indicate an intrinsic dynamic fracture resistance of rocks.}, pages = {10--14}, title = {岩石のシャルピー試験(第1報) --動的破壊エネルギーについて--}, volume = {18}, year = {2006} }
