Stability analysis of second- and fourth-order finite-difference modelling of wave propagation in orthotropic media [PDF]

open access: yes, 2010
The stability of the finite-difference approximation of elastic wave propagation in orthotropic homogeneous media in the three-dimensional case is discussed.

Orthotropic Laminated Plate

open access: yesJournal of the Textile Machinary Society, 1962
目的異方性積層板である強化プラスチックスの強度を支配する要素の一つは, 積層板単位厚さに含まれる補強材であるガラス繊維布の数であるが, この関係はガラス繊維布層に加えられる加圧力にまた支配される.本研究ではまず基本的にガラス繊維布を積み重ねた層は加圧力によって厚さがいかに変化するかの追究を試みた.成果ガラス繊維を平織, 朱子織, あるいはマットとしたものについて種々圧縮試験をおこなった結果, ガラス繊維布層の厚さと加圧力との関係は途中に折曲点のある第1段階と第2段階を経る.その第1段階はきわめて低圧の状態を除いてはlogt0=-mtlogp+b1なる関係があり, 第2段階ではlogt0=-m2logp+b2なる関係があることがわかった.なおm ...

Orthotropic Piezoelectricity in 2D Nanocellulose [PDF]

open access: yesScientific Reports, 2016
AbstractThe control of electromechanical responses within bonding regions is essential to face frontier challenges in nanotechnologies, such as molecular electronics and biotechnology. Here, we present Iβ-nanocellulose as a potentially new orthotropic 2D piezoelectric crystal.

Analysis of Composite Bridge Superstructures Using Modified Grillage Method [PDF]

open access: yesEngineering and Technology Journal, 2009
The analysis principle was used to analyze anisotropic plates (having differentelastic properties and geometries in different directions), the model consists of four sidebeams with flexural rigidity and torsional rigidity and two diagonal beams with only

Wrinkling of Orthotropic Viscoelastic Membranes [PDF]

open access: yes, 2010
This paper presents a simplified simulation technique for orthotropic viscoelastic films. Wrinkling is detected by a combined stress-strain criterion and an iterative scheme searches for the wrinkle angle using a pseudo-elastic material stiffness ...

Experimental study on fatigue performance of UHPC-orthotropic steel composite deck

open access: yesThin-walled structures, 2019
UHPC-orthotropic steel composite deck is an innovative and efficient bridge deck system, however the failure mode of this composite bridge deck under fatigue load is still not well understood, particularly when the deck is in hogging bending.

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.

Bayesian Identification of Elastic Constants in Multi-Directional Laminate from Moir\'e Interferometry Displacement Fields [PDF]

open access: yes, 2013
The ply elastic constants needed for classical lamination theory analysis of multi-directional laminates may differ from those obtained from unidirectional laminates because of three dimensional effects.
