Nearly-incompressible transverse isotropy (NITI) of cornea elasticity: model and experiments with acoustic micro-tapping OCE [PDF]
Scientific Reports, 2020 The cornea provides the largest refractive power for the human visual system. Its stiffness, along with intraocular pressure (IOP), are linked to several pathologies, including keratoconus and glaucoma.

Characterization of transverse isotropy in compressed tissue-mimicking phantoms. [PDF]
IEEE Trans Ultrason Ferroelectr Freq Control, 2015 Tissues such as skeletal muscle and kidneys have well-defined structure that affects the measurements of mechanical properties. As an approach to characterize the material properties of these tissues, different groups have assumed that they are transversely isotropic (TI) and measure the shear wave velocity as it varies with angle with respect to the ...

How does tissue preparation affect skeletal muscle transverse isotropy? [PDF]
J Biomech, 2016 The passive tensile properties of skeletal muscle play a key role in its physiological function. Previous research has identified conflicting reports of muscle transverse isotropy, with some data suggesting the longitudinal direction is stiffest, while others show the transverse direction is stiffest.

TRANSVERSE ISOTROPY IN IDENTICAL PARTICLE SCATTERING [PDF]
Modern Physics Letters A, 2001 It is pointed out that the cross-section for the scattering of identical charged bosons is isotropic over a broad angular range around 90° when the Sommerfeld parameter has a critical value, which depends exclusively on the spin of the particle. This effect is not limited to either Coulomb scattering or bosons, and, as illustrated in the shadow ...

Transverse isotropy in exploration seismics [PDF]
Geophysical Journal International, 1984 Summary. Lamellations – layering on a scale small compared to the wavelengths – result in anisotropy (transverse isotropy) of elastic wave propagation. Since many sedimentary sequences can be regarded as lamellated, one might expect that exploration seismics would be beset with problems resulting from straightforward processing under the assumption of ...

A new fifth parameter for transverse isotropy [PDF]
Geophysical Journal International, 2015 Abstract Properties of a new parameter, ηκ, that is recently introduced by Kawakatsu et al. for transverse isotropy are examined. It is illustrated that the parameter nicely characterizes the incidence angle dependence of bodywave phase velocities for vertical transverse isotropy models that share the same P- and S-wave anisotropy.

Effective Potentials and Elastic Properties in the Lattice-Element Method: Isotropy and Transverse Isotropy [PDF]
Journal of Nanomechanics and Micromechanics, 2017 Lattice approaches have emerged as a powerful tool to capture the effective mechanical behavior of heterogeneous materials using harmonic interactions inspired from beam-type stretch and rotational interactions between a discrete number of mass points.

Thomsen-type parameters and attenuation coefficients for constant-Q transverse isotropy [PDF]
Geophysics, 2023 Transversely isotropic (TI) media with the frequency-independent quality-factor elements (also called “constant- Q” transverse isotropy) are often used to describe attenuation anisotropy in sedimentary rocks.

TRANSVERSE ISOTROPIC CRUST STRUCTURE BENEATH THE NORTHWEST AND CENTRAL NORTH ANATOLIA REVEALED BY SEISMIC SURFACE WAVES PROPAGATION [PDF]
Malaysian Journal of Geosciences, 2021 The Anatolian crust, which is abnormally hot, is widely deformed by subduction related volcanism. Suture zones, transform faults, thrusts and folds and metamorphic core complexes add to the geological complexity.

Effect of transverse isotropy on compressive strengths and elastic properties of bedded gypsum [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2022 Compression tests have been performed on cylindrical specimens of bedded gypsum under confining pressures up to 15 MPa. The specimens contain different bedding plane orientations.
