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.

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%.

Effective Elastic Properties of Cracked Solids: Critical Review of Some Basic Concepts
TL;DR: In this paper, the problem of effective moduli of cracked solids is discussed; they are further assessed by comparing their predictions to results for sample deterministic arrays, and it is argued that, contrary to the spirit of many damage models, there is no direct quantitative correlation between progression of a microcracking solid towards fracture and deterioration of its stiffness; thus, the effective modulations may not always serve as a reliable indicator of damage.

Acoustics of Porous Media
TL;DR: The physical aspects of wave propagation in porous media are discussed in this article, where the authors present a review of experimental techniques and field applications, including wave propagation and vibration in viscoelastic media, and experimental techniques for measuring velocities and attenuations.

Velocity dispersion due to anelasticity; implications for seismology and mantle composition
TL;DR: In this paper, the Boltzmann after-effect equation is solved for a linear anelastic solid having a linear relationship between stress and strain and their first time derivatives, the ‘standard linear solid’, and having a distribution of relaxation times.
Single crystal elastic constants and calculated aggregate properties
TL;DR: In this article, the elastic properties of isotropic aggregates (Young's modulus, Poisson's ratio, shear modulus and bulk modulus) are calculated according to the schemes of Voigt and Reuss.

The Elastic Properties of Composite Materials
TL;DR: In this paper, the problem of determining the elastic properties of composite materials (polycrystals, polycrystals and porous or cracked solids) is approached in several ways, via scattering theory, through variational principles, or by the assumption of specific geometries for the material under consideration.
