Abstract
Brittle fracture of Tennessee Marble, Charcoal Granite and sandstone was studied using the Hopkinson split bar method. The study of the actual fracture behaviour of the rock was possible as no transducers were attached to the specimens themselves. The degree of brittleness of rock was determined by using the attenuation of the first wavefront in a fracturing specimen. There existed a maximum limit to the stress amplitude which could be transmitted through a rock specimen. Fracture is initiated in rock at the same stress under both static and dynamic loads.
