..., the corresponding transmission and reflection coefficients are obtained. Parametric studies are carried out to investigate the influence of joint stiffness, the frequency of incident wave and the position of monitoring point on the transmission and reflection coefficients.

.... The physical properties of rock joints affect the normal and shear strength, deformability, permeability, etc. The test results of Pyrak-Nolte et al. (1990) showed that the dynamic stiffness of rock joints was always higher than the quasistatic stiffness, and the dynamic stiffness was related to the stress...

... ABSTRACT: The gradual transition from stick-slip to stable sliding is studied in lab experiments. The results allow concluding, that the sliding mode and the part of deformation energy spent to the seismic radiation are determined by a ratio of two parameters—the fault stiffness...
