Abstract:

The objective of this program is to determine the effect of strain rate 0.0001-1000sec, 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.
