Multiscale anisotropic fluctuations in sheared turbulence with multiple states [PDF]
, 2017 We use high resolution direct numerical simulations to study the anisotropic contents of a turbulent, statistically homogeneous flow with random transitions among multiple energy containing states.

Transverse isotropy of thinly layered media [PDF]
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 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.

Evaluation on the anisotropic brittleness index of shale rock using geophysical logging
Petroleum, 2023 The brittleness index plays a significant role in the hydraulic fracturing design and wellbore stability analysis of shale reservoirs. Various brittleness indices have been proposed to characterize the brittleness of shale rocks, but almost all of them ...

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.

The Principle of Symmetric Criticality in General Relativity [PDF]
, 2001 We consider a version of Palais' Principle of Symmetric Criticality (PSC) that is applicable to the Lie symmetry reduction of Lagrangian field theories. PSC asserts that, given a group action, for any group-invariant Lagrangian the equations obtained by ...

Modeling of fiber circumplacement around a hole using a streamline approach
Universal Journal of Mathematics and Applications, 2018 The insertion of holes into laminates can be done by producing a fiber reinforced composite plate and, subsequently, drilling the borehole. Alternatively, we can bypass the fibers around the final hole before injecting the matrix material.
