STRENGTH AND DEFORMATION PROPERTIES OF GRANITE, BASALT, LIMESTONE AND TUFF AT VARIOUS LOADING RATES

The objective of the work reported herein was to determine the strength and stress-strain characteristics of rocks of four types under various rates of loading. This was accomplished by conducting slow (specimens loaded at rates of less than 2,251 psi/sec) and rapid (specimen loaded at rates greater...

Zusammenfassung:The objective of the work reported herein was to determine the strength and stress-strain characteristics of rocks of four types under various rates of loading. This was accomplished by conducting slow (specimens loaded at rates of less than 2,251 psi/sec) and rapid (specimen loaded at rates greater than 2,251 psi/sec) unconfined compression tests, tensile splitting tests, and triaxial compression tests utilizing confining pressures ranging from 250 to 5, 000 psi. Granite, basalt, limestone, and tuff from the Atomic Energy Commission's Nevada Test Site, Mercury, Nevada, were used in this program. Nondestructive tests such as specific gravity, porosity, and compressional wave velocity were conducted on all specimens to determine homogeneity of each rock.
