Estimates of fluid pressure and tectonic stress in hydrothermal/volcanic areas:a methodological approach... The analytical procedure requires the
coefficient of internal friction, cohesion, rock density, and thickness of overburden to be known from geological
data....
Fault zone strength and failure criteria, geophys... I test and reject the hypothesis that fault zone strength and apparent coefficient of internal friction can be predicted from fracture of intact rock simply by accounting for differences in the failure laws and without considering variations in the...
Reply to comment on "fault zone strength and failure criteria"... There are two basic problems with the LBS analysis: 1) they suggesthat an empirical relation has been established between the coefficient of internal friction of intact rock gi and the coefficient of friction of fault gouge g,, yet their analysis does not inwhere •, is the apparent friction angle....
Shear test results for cohesion and friction coefficients for different granular materials: scaling implications for their usage in analogue modelling... Shear stress has been plotted against normal stress in order to determine the cohesion and coefficient of internal friction for the investigated materials....
