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: This analysis provides the DRP community with a range of possible outcomes which can be expected depending on the solver and its setup, and falls within the ranges consistent with the relevant laboratory data.

The brittle-ductile transition in porous rock: A review
Teng-fong Wong,Patrick Baud +1 more
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%.

Pore fluids and seismic attenuation in rocks
Kenneth W. Winkler,Amos Nur +1 more
TL;DR: In this paper, the authors measured attenuation and velocities in resonating bars of Massilon sandstone at various degrees of saturation and found that shear energy loss simply increases with degree of saturation, whereas bulk compressional energy loss increases to ∼95% saturation and then rapidly decreases as total saturation is achieved.

New analysis of attenuation in partially melted rock
TL;DR: In this article, a model of partially melted rock is analyzed in which melt occurs as thin films along grain boundaries, and the liquid phase is assumed to be a dispersion of randomly oriented ellipsoidal inclusions with minor axes much smaller than major axes.

Elasticity of some high-density crystals
TL;DR: The adiabatic elastic constants of two garnets (spessartite-almandite and almandite), spinel (synthetic), rutile and olivine are reported in this paper.

An Ultrasonic Study of the Area of Contact between Stationary and Sliding Surfaces
Kevin Kendall,David Tabor +1 more
TL;DR: In this article, the authors used an ultrasonic wave to measure the elastic stiffness of the interface and found that the stiffness of a single circular contact is proportional to the diameter of the contact and not to its area.
Journal ArticleDOI
Estimating Mechanical Properties of Shale From Empirical Correlations
TL;DR: In this article, the authors present empirical correlations to assist in predicting shale mechanical properties, based on extensive laboratory testing of shale cores primarily from the North Sea, and the acoustic P-wave velocity is a primary input parameter in several of the correlations.
