Fracture and flow of rocks under stress and their geophysical and seismological implications raise fundamental questions in rock mechanics, particularly in the areas of tectonophysics and seismology. This text exclusively addresses the deformation and fracture of rock specimens under general triaxial compression, in which all three principal stresses are different; which significantly affects the ultimate strength of rocks. It moreover deals with deformation and failure following intermediate principal stress in graphic and numerical form. The effect of the intrinsic features of rock masses of inhomogeneous or anisotropic structure are taken into account, as are acoustic emission phenomena in rocks under various stress states. Friction in rocks, measured by a newly-designed shear-testing machine, is discussed in relation to earthquake phenomena.
Exclusive and prominent account on experimental rock mechanics.
"In summary, this is a superior book for anyone interested in studying Mogi’s long and uniquely fruitful research career in rock mechanics applied to mechanisms of faulting and earthquakes."
