Finite-frequency sensitivity of body waves to anisotropy based upon adjoint methods [PDF]
, 2007 We investigate the sensitivity of finite-frequency body-wave observables to mantle anisotropy based upon kernels calculated by combining adjoint methods and spectral-element modelling of seismic wave propagation.

Stress-dependent shear wave splitting and permeability in fractured porous rock
Journal of Rock Mechanics and Geotechnical Engineering, 2019 It is well known that shear wave propagates slower across than parallel to a fracture, and as a result, a travelling shear wave splits into two directions when it encounters a fracture.

Wave speeds and Green’s tensors for shear wave propagation in incompressible, hyperelastic materials with uniaxial stretch [PDF]
, 2019 Assessing elastic material properties from shear wave propagation following an acoustic radiation force impulse (ARFI) excitation is difficult in anisotropic materials because of the complex relations among the propagation direction, shear wave ...

High temperature elastic anisotropy of the perovskite and post-perovskite polymorphs of Al2O3 [PDF]
, 2005 Finite temperature ab initio molecular dynamics calculations were performed to determine the high temperature elastic and seismic properties of the perovskite and post-perovskite phases of pure end-member Al2O3.

Mid-mantle deformation inferred from seismic anisotropy [PDF]
, 2002 With time, convective processes in the Earth's mantle will tend to align crystals, grains and inclusions. This mantle fabric is detectable seismologically, as it produces an anisotropy in material properties—in particular, a directional dependence in ...

Seismic anisotropy beneath the Chinese Mainland: Constraints from shear wave splitting analyses
Earthquake Research Advances, 2021 We use earthquakes recorded by the China National Seismic Network from 2015 to 2019 and measure shear wave splitting parameters of SKS to study the anisotropic characteristics beneath the mainland of China.

Deriving micro- to macro-scale seismic velocities from ice-core c axis orientations [PDF]
The Cryosphere, 2018 One of the great challenges in glaciology is the ability to estimate the bulk ice anisotropy in ice sheets and glaciers, which is needed to improve our understanding of ice-sheet dynamics.
