Anisotropic Damage to Hard Brittle Shale with Stress and Hydration Coupling

Anisotropic Damage to Hard Brittle Shale with Stress and Hydration Coupling

Acoustic-wave velocities of shale rocks with different coring angles were tested by an acoustic-emission experiment under different confining pressures and soaking time of drilling fluid. Effects of stress and hydration coupling on the acoustic-wave velocities, elastic parameters, and anisotropic da...
