Transverse isotropy in magnetoactive elastomers
Journal of Magnetism and Magnetic Materials, 2021Abstract Magnetoactive elastomers (MAEs) are field-controllable materials with magnetically switchable properties. The presence of an external magnetic field results in the change in the macroscopic shape of the MAE. The magnetic field also introduces a mechanical anisotropy with an axis of symmetry along the magnetic field.

Fluids with Transverse Isotropy as Models for Electrorheological Fluids
ZAMM, 1998Summary: In electrorheological fluids (ER-fluids) fibers are formed upon application of an electric field. This renders the fluid transversely isotropic. Studying transverse isotropy from a purely phenomenological point of view in its simplest form reveals that yield stresses have to be reckoned with, be they shear stresses or normal stresses.

Unexpected Consequences of Transverse Isotropy
Bulletin of the Seismological Society of America, 2020ABSTRACTIn a series of articles, Kawakatsu et al. (2015) and Kawakatsu (2016a,b, 2018) introduced and discussed a new parameter, ηκ, that characterizes the incidence angle dependence (relative to the symmetry axis) of seismic body-wave velocities in a transverse isotropy (TI) system. During the course of these exercises, several nontrivial consequences

Seismic traveltime inversion for transverse isotropy
Geophysics, 1990Abstract Quantitative measurements of seismic anisotropy can provide a valuable clue to the lithology and degree of stratification in sedimentary rocks with hydrocarbon potential. We present a practical technique for obtaining anisotropy parameters (i.e., five stiffness coefficients A, C, F, L, and M) from seismic traveltime ...

ANISOTROPY AND TRANSVERSE ISOTROPY*
Geophysical Prospecting, 1986ABSTRACTA number of authors in the exploration literature have written about anisotropy, but have restricted their discussions to wave propagation through rock having transverse isotropy with a vertical symmetry axis. This note shows that there are fundamental differences between transverse isotropy when the symmetry axis is vertical (normal to the ...

Inversion of reflection traveltimes for transverse isotropy
Geophysics, 1995Abstract In anisotropic media, the short-spread stacking velocity is generally different from the root-mean-square vertical velocity. The influence of anisotropy makes it impossible to recover the vertical velocity (or the reflector depth) using hyperbolic moveout analysis on short-spread, common-midpoint (CMP) gathers, even if both P-

Effects and Consequences of Transverse Isotropy in the Seafloor
1986Transverse isotropy, a form of anisotropy with a single vertical axis of symmetry, is extremely widespread in marine sediments, but its effects on seismic interpretations have been inadequately quantified. This anisotropy increases with depth, just as propagation velocities themselves increase.
