In general terms a fabric filter system consists of a porous flexible layer of textile material through which a dusty gas is passed to separate particles from the gas stream. Deposits on the textile are removed periodically by powerful moving and thereby cleaning of the cloth to maintain the pressure drop across the filter within practical operating limits. There are several methods to make the...

Unit cell homogenization techniques are applied on multiple length scales to compute the macroscopic hyperelastic stiffness characteristics of textile-reinforced polymer matrix composites. On the smallest scale (~50μm) the effective transversely isotropic properties of tows (or yarns) are computed based on both fiber and matrix properties. These position-dependent transversely isotropic effecti...

Color is defined as “ the sensation experienced or caused by light reflected from or transmitted through objects”. In the strict sense, we cannot directly measure perceived color, however we can measure and subsequently calculate certain factors which are responsible for producing this sensation of color. The quantification of the color properties of textile materials is of great economic value...

This paper describes the benefits of and issues in designing and building an integrated, body-worn electronic textile (e-textile) system capable of assessing a suite of biomechanical measures. Unlike laboratorybased systems, this system would be worn by a soldier and could be used in a range of environmental conditions. A prototype e-textile developed at Virginia Tech has already shown promisin...

Local scouring around bridge piers is a natural phenomenon caused by the erosive process of flowing stream on alluvial beds. The 3D flow field around bridge piers interacting with the bed materials increases complexity of local scour process. The local scour depth develops in accelerated flows and if it is not predicted correctly, the bottom level of local scour hole will exceed the original le...

Abstract Scouring is a complex process dependent on several factors, and local scour more than general scour. This study was an attempt to predict round bridge piers based in the water stream. Three obstacle shapes were used – circular, round-nosed, elliptical as they are predominant hydraulic structures like piers. For each shape, depth measured around periphery for five gradually increasing d...
