FRACTURE OF ROCK DUE TO HIGH PRESSURE, SHORT DURATION LOADINGS.
Abstract
The results of a preliminary theoretical and experimental research program investigating the dynamic fracture of rock due to high pressure, short duration loadings are presented. Efforts were centered on hypothesizing a dynamic failure mechanism and verifying this model by a small number of laboratory experiments. The model proposed is one where the statistical stress distribution accounts for the initiation of failure events and the duration of the stress determines the coalescence of these failure events into failure surfaces. The experimental program defined the regimes in which stress and geometric parameters affect the dynamic failure; very general correlation between the experiments and theory was possible. (Author)
