Effects of two parallel fractures with nonlinear deformational behavior on one-dimensional P-wave propagation
By X. B. Zhao, J. G. Cai
When stress wave propagates through fractured rock masses, the wave will be slowed and attenuated due to the presence of these fractures. If the amplitude of stress wave is large enough to mobilize no
