A higher order triangular plate finite element using Airy functions

open access: yesAdvances in Mechanical Engineering, 2020
The present paper describes the formulation of a new moderately thick plate bending triangular finite element based on Mindlin–Reissner plate theory. It is called a Great Triangular Moderately Thick Plate Finite Element, or GTMTPFE.

Second-order Stokes wave-induced dynamic response and instantaneous liquefaction in a transversely isotropic and multilayered poroelastic seabed

open access: yesFrontiers in Marine Science, 2022
The ocean waves exhibit obvious non-linearity with asymmetric distribution of wave crests and troughs, which could induce significantly different effect on the seabed compared to the commonly used linear wave theory.

Modelling Elastic Behaviour of Soft Tissues. Part II. Transverse Isotropy

open access: yesEngineering Transactions, 2015
New constitutive relationships for hyperelastic transversely isotropic materials have been proposed. The well-known isotropic hyperelastic model due to OGDEN 11.581 has been extended to transverse isotropy.

Deformation Development Mechanism in a Loess Slope With Seepage Fissures Subjected to Rainfall and Traffic Load

open access: yesFrontiers in Earth Science, 2021
Loess landslides induced by rainfall and traffic load are significant hazards during the construction and operation of highways in many loess-covered areas. Studies of the deformation and stability of loess slopes with seepage fissures are limited.

Effect of Soil Anisotropy on Ground Motion Characteristics

open access: yesBuildings, 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

Isotropy or weak vertical transverse isotropy in D″ beneath the Atlantic Ocean [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2004
Shear velocity properties of D″ beneath the central Atlantic Ocean are explored using predominantly European seismic recordings of intermediate and deep focus (>100 km) South American earthquakes. Broadband data are analyzed and, when possible, corrected for upper mantle models of receiver‐side anisotropic structure.

Spin Diffusion in Trapped Gases: Anisotropy in Dipole and Quadrupole Modes [PDF]

open access: yes, 2006
Recent experiments in a mixture of two hyperfine states of trapped Bose gases show behavior analogous to a spin-1/2 system, including transverse spin waves and other familiar Leggett-Rice-type effects.

THE FINITE ELEMENT STRESS STATE ANALYSIS OF UNDERGROUND HYDRAULIC ERECTIONS TAKING INTO ACCOUNT THE ANISOTROPY OF THE MEDIUM

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2017
In this article, the stressed state analysis of a transverse-isotropic rocky soil near a hydrotechnical tunnel is carried out. The cross section of the tunnel is circular.

Assessing the Permeability in Anisotropic and Weakly Permeable Porous Rocks Using Radial Pulse Tests

open access: yesOil & 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 ...

Bedding plane-embedded augmented virtual internal bonds for fracture propagation simulation in shale

open access: yesTheoretical 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
