Journal of Rock Mechanics and Geotechnical Engineering, 2023 In recent decades, low-frequency (LF) experiments based on the forced-oscillation (FO) method have become common practice in many rock physics laboratories for measuring the elastic and anelastic properties of rocks.

Elastic and anelastic adjoint tomography with and full Hessian kernels [PDF]
Geophysical Journal International, 2023 SUMMARYThe elastic and anelastic structures of the Earth offer fundamental constraints for understanding its physical and chemical properties. Deciphering small variations in the velocity and amplitude of seismic waves can be challenging. Advanced approaches such as full-waveform inversion (FWI) can be useful.

Elastic, anelastic, and piezoelectric coefficients of GaN [PDF]
Journal of Applied Physics, 2012 We report elastic, anelastic, and piezoelectric coefficients of wurtzite GaN measured by resonant-ultrasound spectroscopy coupled with laser-Doppler interferometry. Five rectangular parallelepiped specimens, measuring 6.5 × 2.0 × 4.0 mm3, cut from two single crystals were used.

Complex rays in elastic and anelastic media [PDF]
Geophysical Journal International, 1994 SUMMARY The concept of complex rays plays an important role in wave-propagation modelling. In this study we describe an efficient method for complex ray tracing. Our objective is to facilitate generalization of this concept to wave-propagation studies in general inhomogeneous media.

Compressional wave dispersion due to rock matrix stiffening by clay squirt flow
Geophysical Research Letters, 2016 The standard Biot‐Gassmann theory of poroelasticity fails to explain strong compressional wave velocity dispersion experimentally observed in 12 tight siltstone with clay‐filled pores.

Anelastic deformation of magnesium and its alloys – A review
Smart Materials in ManufacturingThe deformation of Mg is made up of elastic, anelastic and plastic components. Unlike the elasticity and plasticity which have been widely studied, the anelasticity has been routinely ignored in many published works when characterising the behaviour of ...

A Nanoindentation Study of Attenuation in Geological Materials
Earth and Space ScienceThe dissipation of elastic strain energy, or attenuation, in Earth materials contributes to a range of geophysical phenomena, such as the damping of seismic waves and tidal heating of planetary bodies. We present a new method for measuring attenuation in

A Geometric Theory of Surface Elasticity and Anelasticity
Journal of Nonlinear ScienceAbstract In this paper we formulate a geometric theory of elasticity and anelasticity for bodies containing material surfaces with their own elastic energies and distributed surface eigenstrains. Bulk elasticity is formulated in the language of Riemannian geometry, and the framework is extended to material surfaces by using the ...
