Anisotropy is ubiquitous in the Earth's crust, which causes the elastic characteristics of
seismic waves to change with direction. The study of seismic wave anisotropy is of great …

A nonlinear elastic model for acoustic waves in a stressed medium is used to calculate
tectonic stress-induced changes in borehole flexural dispersions. Our theoretical analysis …

We develop a rock physics model based on nonlinear elasticity that describes the
dependence of the effective stiffness tensor as a function of a 3D stress field in intrinsically …

We show both experimentally and theoretically how stress concentrations affect the velocity
field around a borehole, and how the velocity field influences dipole anisotropy …

A new 3D cylindrical perfectly matched layer (PML) formulation is developed for elastic wave
propagation in a pressurized borehole surrounded by a triaxially stressed solid formation …

We described a nondestructive method to estimate the maximum and minimum horizontal
stresses and formation nonlinear elastic constants using sonic data from a vertical wellbore …

A heterogeneous medium composed of inviscid fluid and solid constituents is pre-stressed,
resulting in relative slip of material particles at the interfaces between the solid and the fluid …

The reflection and transmission of elastic waves are of great significance for predicting
reservoir physical properties, interpreting seismic data and detecting crustal structures. Most …

Understanding the stress dependence of elastic properties of rocks is important for reservoir
characterization and seismic‐hazard monitoring. Several known approaches describing this …

The development of a dual-mode thickness-shear quartz pressure sensor to meet the
