A Study of the Dynamic Strength and Fracture Properties of Rock

Abstract

The objective of this program is to determine the effect of strain rate (0.0001-1000/sec), temperature (80 - 800K) and confining pressure (0 - 7 Kbars) on the strength properties of hard rock. Compression tests have been performed on Dresser basalt using hydraulic test equipment at the lower rates and Hopkinson pressure bar apparatus at the highest rates.
