Development of Transversely Isotropic Elastoplastic Constitutive Model in FLAC3D and Its Application in Tunnel Engineering

open access: yesGeofluids, 2022
The obvious anisotropy of layered rock mass prevents the built-in constitutive model of commercial simulation software from accurately describing the elastoplastic behavior of the rock mass.

Prediction of bulk mechanical properties of PVC foam based on microscopic model:Part II-Material characterization and analytical formulae

open access: yesPolymer Testing, 2023
The bulk mechanical properties of a foam are strongly related with the modulus of elasticity and yield strength of the base material and the geometric features of the foam microstructure.

Rayleigh waves speed in transversely isotropic material

open access: yesEngineering Transactions, 2006
Rayleigh wave speed in transversely isotropic material is studied. A very simple technique is adopted to solve the secular equation. Speed in some transversely isotropic materials is calculated.

Effect of an orientation-dependent non-linear grain fluidity on bulk directional enhancement factors

open access: yesJournal of Glaciology, 2021
Bulk directional enhancement factors are determined for axisymmetric (girdle and single-maximum) orientation fabrics using a transversely isotropic grain rheology with an orientation-dependent non-linear grain fluidity.

Hydrostatic compression on polypropylene foam [PDF]

open access: yes, 2008
Models currently used to simulate the impact behaviour of polymeric foam at high strain rates use data from mechanical tests. Uniaxial compression is the most common mechanical test used, but the results from this test alone are insufficient to ...

Transversely Isotropic Problems [PDF]

open access: yes, 2019
A transversely isotropic medium is a medium, which has a favored direction and is isotropic in the plane perpendicular to this direction. Among crystalline media, all materials with a hexagonal crystal system belong to this class: they are elastically isotropic in the plane perpendicular to the hexagonal axis.

Dispersion equation of Rayleigh waves in transversely isotropic nonlocal piezoelastic solids half-space

open access: yesVietnam Journal of Mechanics, 2019
This study is devoted to investigate the propagation of Rayleigh-type waves in transversely isotropic nonlocal piezoelastic half-space.  When the stress-free boundary is maintained at charge-free condition, the dispersion equation for the propagation of

Analytical Solution of Stress in a Transversely Isotropic Floor Rock Mass under Distributed Loading in an Arbitrary Direction

open access: yesApplied Sciences, 2021
Rock masses with a distinct structure may present a transversely isotropic character; thus, the stress state in a transversely isotropic elastic half-plane surface is an important way to assess the behavior of the interaction between the distributed ...
