An Experimental Study on Determination of Crack Propagation Energy of Rock Materials Under Dynamic Impact and Static Loading Conditions

The Charpy impact test, a widely applied impact strength determination test for various materials such as metals, polymers and cementitious materials was performed to evaluate the crack propagation energy of 13 different granite type rock materials under the impact load condition. Additionally, c...

description The Charpy impact test, a widely applied impact strength determination test for various materials such as metals, polymers and cementitious materials was performed to evaluate the crack propagation energy of 13 different granite type rock materials under the impact load condition. Additionally, crack propagation energies of the granite materials were determined under the static load condition to compare the results with those of the Charpy impact test. The energy levels measured from static load tests were significantly lower than those obtained from the dynamic load test that the ratio of energy level under the dynamic loading to energy level under static loading condition was measured to change between 39 and 200 for different 13 type of granite materials tested in this study. The crack propagation time for the chevron-notched specimens under static loading was also measured using professional sound recording systems. As results of this study have not indicated that the crack propagation speed and energy values measured from different granite materials have a direct relationship, energy-dependent crack propagation speed was found to be an inherent property of rock materials. The Charpy impact test was assessed usable for being a sensitive crack propagation energy determination method for rock materials. In the context of improvement of the Charpy impact test for rock materials, some issues were pointed out in this study
