Measurements of linear strain, ultrasonic velocity, and attenuation (Q−1) were made simultaneously as functions of confining pressure on core and outcrop samples from the Moodus, Connecticut, area. Strain measurements indicate the core samples cont

The occurrence of microcracks and pore space reduces the P and S wave velocities in rocks from those expected for the intrinsic mineral matrix. In the low-pressure regime, before microcracks close, the elastic properties and wave velocities are chara

We present new elasticity measurements on single-crystal fayalite and combine our results with other data from resonance, pulse superposition interferometry, and Brillouin scattering to provide a set of recommended values for the adiabatic elastic mo

Boron suboxide compounds are of interest because of their low densities coupled with high hardness. In the present study, we have attempted to determine the nature of the BxO phases that occur in the field defined by pressures of zero to 1.5 GPa, tem

In an effort to better understand the structural dynamics of glasses, we have measured the second-order adiabatic elastic moduli, and their pressure and temperature derivatives, of a sodium silicate and a sodium alumino-silicate glass. In both cases,

The longitudinal and transverse ultrasonic wave velocities of polycrystalline BaVS3 have been measured over a temperature range 40 K to 350 K. At 258 K the material undergoes a structural phase transition from a hexagonal to an orthorhombic form. Alt

The effects of irradiation on the coefficient of thermal expansion (CTE), the density, and the elastic moduli of low-CTE materials such as amorphous SiO2, ultra-low-expansion glass, β-SiC, Astrositall, and Zerodur were surveyed. It was found that th

The isotropic elastic moduli of four specimens of nitrogen-stabilized cubic aluminum oxide (ALON) were measured using pulse superposition interferometry. Experiments were carried out as a function of both pressure (ambient to 1 GPa) and temperature (

The elastic moduli of several organometallic silica gels were measured using pulse-superposition interferometry (PSP). A series of gels were prepared under acid-catalyzed conditions where the molar ratio of water to tetraethoxysilane (TEOS) in the so
