    Abstract: Rock fracture and its failure with time due to external forces and other factors such as fluids, temperature have always been a major concern in rock engineering and construction. Based on thermodynamics and theory of solid physics, authors propose an energy criterion for rheological failure of rock, which considers two effects: (1) energy dissipat... Show More
