Principles of rock mechanics
The principles of rock mechancis explains the fundamental concepts of continuum mechanics and rheology as applied in studies of rock deformation. A thorough understanding of rock behavior is essential for strategic planning in the petroleum and mining industry, in construction operation, and in locating subsurface repositories. The formation of geological structures or rock deformation patterns, studied by geodynamicists and tectonicians, is, also governed by the mechanical principles outlined i
