Empirical relations between elastic wavespeeds and density in the Earth's crust
TL;DR: A compilation of compressional-wave (V p) and shear-wave velocities and densities for a wide variety of common lithologies is used to define new nonlinear, multivalued, and quantitative relations between these properties for the Earth's crust as mentioned in this paper.

TL;DR: A review of the current understanding of phenomena involved in gas hydrate formation and the physical properties of hydrate-bearing sediments can be found in this paper, where the magnitudes and interdependencies of these properties are critically important for predicting and quantifying macroscale responses of hydrates to changes in mechanical, thermal, or chemical boundary conditions.

TL;DR: In this article, Bifurcation analysis can be used in conjunction with a constitutive model to predict the onset of strain localization, which is in qualitative agreement with the laboratory data.

Computation of linear elastic properties from microtomographic images: Methodology and agreement between theory and experiment
TL;DR: In this article, the elastic properties of the digitized images under dry, water-saturated, and oil -saturated conditions were derived from a suite of four samples of Fontainebleau sandstone with porosities ranging from 7.5% to 22%.

Dynamic poroelasticity: A unified model with the squirt and the Biot mechanisms
Jack Dvorkin,Amos Nur +1 more
TL;DR: In this article, the velocity dispersion and attenuation of seismic and acoustic waves in rocks with fluids are affected by the two most important modes of fluid/solid interaction: (1) the Biot mechanism where the fluid is forced to participate in the solid's motion by viscous friction and inertial coupling, and (2) the squirt-flow mechanism where fluid is squeezed out of thin pores deformed by a passing wave.

Microcrack-induced elastic wave anisotropy of brittle rocks
Colin M. Sayers,Mark Kachanov +1 more
TL;DR: In this article, the authors measured the elastic wave velocities in the presence of open micro-cracks and fractures and compared them with the measurements of the ultrasonic compressional and shear wave velocity for propagation parallel and perpendicular to an increasing axial stress applied at constant confining stress to Berea sandstone.

Amos Nur,Gene Simmons +1 more
TL;DR: In this article, the authors apply uniaxial stress to a sample of granite and show that elastic wave velocity anisotropy increases with increasing stress, exhibiting acoustic double refraction.
