TL;DR: In this paper, the authors derived the complete solutions for seismic wave reflection, conversion, and transmission across a displacement and velocity discontinuity between two half-spaces with different densities and elastic properties for all angles of the incident wave.

TL;DR: In this paper, the relationship between fracture specific stiffness and fluid flow through a fracture fall into two general classes of behavior: (1) Fractures either fall on a loosely defined universal curve relating fluid flow to fracture-specific stiffness, or (2) the flow is weakly dependent on fracture specific stiffness.

TL;DR: In this article, the effects of nonwelded interfaces on seismic wave propagation are analyzed using effective moduli, in terms of which seismic wave propagates independent of frequency and without loss, unless the moduli include imaginary terms.

TL;DR: In this article, the authors present the results of a workshop sponsored by the U.S. Department of Energy (DOE), Office of Science, Office of Basic Energy Sciences, Chemical Sciences, Geosciences, and Biosciences Division that was held in Leesburg, Virginia in May 2016.

TL;DR: In this paper, large deviations from "cubic-law" dependence of laminar fluid flow through fractures on the apparent mechanical aperture of a fracture can be explained by assuming: 1) cubic-law dependence of flow on the actual local aperture at the microscopic level; 2) conservation of rock volume when deforming the fracture; and 3) macroscopic flow properties are dominated by the critical neck.
