“…Hofstee et al [62] proposed to simulate the shear deformation of woven fabrics by the help of fishnet approach, described earlier, but replacing the fishnet segments (assumed to be inextensible sections, representing yarns, Fig. 20 Sliding in the two main directions of the square sample for the experiment and the simulation according to the direction a x; b y [60] connected by pivots) with the 3D RUC of typical crimped pattern (Fig.…”

To cite this version:Elena Syerko, Sébastien Comas-Cardona, Christophe Binetruy. Models for shear properties/behavior of dry fibrous materials at various scales: a review.Abstract During forming operations of dry fibrous materials in order to get the composite preforms, the deformation mode is substantially determined by the occurring shear strains. Consideration of the material shear response namely from the theoretical point of view has gained high importance because multi-scale nature and anisotropy of fibrous materials complicates their experimental investigation, which raises the question of the tests realizability, complexity, and cost. This work analyses and classifies the existing theoretical approaches for the shear prediction with respect to the mathematical principles employed, as well as with respect to the architecture of diverse fibrous materials, to which the approach can be applied. Both classifications depend in turn on the main criterion of classification emphasized here -the scale of observation of the shear load. According to the theoretical framework, the approaches form the main groups based either on purely geometrical reasoning, or on finite elements analysis, or on energy minimization, or on forces equilibrium principle. The approaches are compared according to the total of mechanical factors included in their analysis and typical for a certain stage of shear load and a certain scale (micro-, meso-, or macro-). The advantages and difficulties of each of the methods are evaluated.

“…There are also reported investigations on the draping behaviors of multi-layer textiles using digital image processing [11,12]. As expected, the challenging question of theoretical modeling of fabric drape phenomena has attracted much interest [13][14][15][16] [17][18][19][20][21][22][23][24][25][26][27].…”

With huge varieties of fabrics, the first challenge for any performance evaluation is to categorize the vast types of the products into fewer, more homogeneous and thus akin groups. Classification or sorting is arguably the first step of any scientific investigation, and comparison of product quality is meaningful only when conducted within a group of comparable products. A new criterion termed fabric linear density λ is first proposed in this paper so that fabrics can in general be divided into 4 groups. The derivation and validation of this parameter are provided.The importance of fabric drape is almost self-evident, but there is still no effective ways to measure this fabric attribute. The Cusick Drapemeter suffers from its low repeatability and low sensitivity, and is hence not widely or frequently used. The PhabrOmeter, along with the fabric linear density λ, is proposed and demonstrated in this study as a much more efficient alternative for fabric drape test. By actually testing 40 various fabrics, the principle, procedure and results of this method is presented in this paper. IntroductionVisual attributes of textile fabrics represent a sub-group of sensory properties, perceived particularly by visual sense of consumers. Such visual qualities include fabric drape, surface state and luster, and, by logical extension, the fabric wrinkle recovery, fabric surface retention and stain resistance, i.e., all fabric appearance related esthetic characteristics. We call them fabric attributes to differentiate from the term fabric properties such as the fabric weight and fabric strength, for the latters are much easier to describe and with definitions widely accepted, and measurement methods well established.

“…This description can be refined, using the so-called meso-macro models that account for the nonlinearities due to the change of undulations of the yarns [8,12]. A synthetic view of the modeling of woven structures is given in [13].…”
