A Study of the Dynamic Strength and Fracture Properties of Rock

Abstract

The report summarizes the results of a study aimed at developing a quantitative failure strength criterion for Dresser basalt, as well as gaining better understanding of the basic fracture mechanisms involved in fracture. Tests were performed over a temperature range of 77-1400K, a strain rate range of .0001-1000 sec minus 1, pressures of 0-100 KSI, and under a variety of uniaxial and biaxial stress states. Failure theories were analyzed, and microfracture was studied extensively.
