Transverse isotropy of thinly layered media [PDF]
Geophysical Journal International, 1984 Summary. Three problems of seismic anisotropy in thinly layered media (TPM) are discussed: (1) A dependence is established for the character of the ray velocity of longitudinal low-frequency waves on the ratio of P- and S-wave velocities in thin layers. (2) Conditions are specified for cusps on SV-wave surfaces.

Assessing the Permeability in Anisotropic and Weakly Permeable Porous Rocks Using Radial Pulse Tests
Oil & Gas Science and Technology, 2014 The pulse test is usually considered to be an efficient method for measuring the permeability of weakly permeable porous rocks. Classically, the test consists of imposing a pressure drop on the base of a cylindrical sample and measuring the pressure ...

Effect of Soil Anisotropy on Ground Motion Characteristics
Buildings, 2023 Soil transverse isotropy results in different stiffness characteristics in horizontal and vertical directions. However, the effect is usually neglected in seismic motion analysis. In this study, an equivalent linear anisotropic soil model was established

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.

Bedding plane-embedded augmented virtual internal bonds for fracture propagation simulation in shale
Theoretical and Applied Mechanics Letters, 2021 To effectively simulate the fracture propagation in shale, the bedding plane (BP) effect is incorporated into the augmented virtual internal bond (AVIB) constitutive relation through BP tensor. Comparing the BP-embedded AVIB with the theory of transverse

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.

New refined model for curved linear anisotropic rods with circular cross section
Applications in Engineering Science, 2021 An asymptotic reduction method is introduced to construct a curved rod theory for a general anisotropic linearized elastic material. For the sake of simplicity, the cross section is assumed to be circular.
