Influence of woven ply degradation on fatigue crack growth in thin notched composites under tensile loading [PDF]
, 2010 This paper deals with the fatigue of the through the-thickness crack propagation in thin notched composite laminates made of two glass woven plies. It highlights the different crack growths between warp and weft directions of the woven ply.

Journal of Engineered Fibers and Fabrics, 2023 On a loom, the warp yarns experience exceptionally high mechanical stresses and strains, as well as significant abrasion from friction. As a result, significant yarn breakages cause loom stoppages and, hence, production and quality interruptions.

Non-Abelian (p,q) Strings in the Warped Deformed Conifold [PDF]
, 2006 We calculate the tension of $(p,q)$-strings in the warped deformed conifold using the non-Abelian DBI action. In the large flux limit, we find exact agreement with the recent expression obtained by Firouzjahi, Leblond and Henry-Tye up to and including ...

Warp Tension of Tricot Machines
Journal of the Textile Machinary Society, 1963 目的 定常状態で編成中のトリコット機のたて糸送出し量を変化させた場合の張力の過渡応答を測定して, 両者の一般的な関係を明らかにすることを目的とした. 成果 (1) トリコット機で編成中にたて糸送出し量が変化した場合の, 1コース編成中に生ずる張力の最大値の過渡現象は, 線型オペレータG (P) =E/ (1+T1・P), E : 定数, T1 : 時定数, を単位時間のたて糸巻きとり量と送出し量の差に作用させることによって推定できる.(2) 上記オペレータ中の時定数T1の値は, たて糸送出し量を増加させた場合の方が減少させた場合より小さい.またT1は機械の回転数に依存し, たて糸送出し量が増加する場合は回転数が増すと減少し, たて糸送出し量が減少する場合は回転数が増すと増加する ...

Mechanical properties of coated fabric membranes at high temperature
Journal of Engineered Fibers and Fabrics, 2022 A model about the strength of polyvinyl chloride coated polyester at high temperature was proposed in this paper. The model can predict the warp-direction strength, weft-direction strength, and off-axis strength at high temperatures according to the ...

Fatigue crack growth in thin notched woven glass composites under tensile loading. Part II: modelling [PDF]
, 2011 Fatigue propagation of a through-the-thickness crack in thin woven glass laminates is difficult to model when using homogeneous material assumption. Crack growth depends on both the fatigue behaviour of the fibres and of the matrix, these two phenomena ...

The General Warped Solution with Conical Branes in Six-dimensional Supergravity [PDF]
, 2005 We present the general regular warped solution with 4D Minkowski spacetime in six-dimensional gauged supergravity. In this framework, we can easily embed multiple conical branes into the warped geometry by choosing an undetermined holomorphic function ...

A Statistical Approach for Obtaining the Controlled Woven Fabric Width
AUTEX Research Journal, 2015 A common problem faced in fabric manufacturing is the production of inconsistent fabric width on shuttleless looms in spite of the same fabric specifications. Weft-wise crimp controls the fabric width and it depends on a number of factors, including warp
