Özet:

 

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.
