Shear deformation analysis for woven fabrics

Shearing Properties of the Skewed Woven Fabrics (RESEARCH NOTE)

Simulate the Dynamic Draping Behavior of Woven and Knitted Fabrics

In this article a practical mass-spring system was developed to simulate the draping of woven and knitted fabrics. The material properties important to fabric drape, including aerial density, tensile, shear, and bending properties were measured using the Kawabata Evaluation System and the experimental data were incorporated into the mass-spring model to simulate the dynamic draping behavior of ...

An Analytical Study of Initial Shear Behavior of Plain Woven Hybrid Fabrics

During recent years, the fabrics made from different yarns have been used for industrial purposes such as composite materials. Given the importance of the shear properties of these fabrics, a mechanical model based on the Grosberg and Park's Model for hybrid plain-woven fabrics is proposed. In this model, using the Energy method, the initial load-shear angle behavior of hybrid fabrics is calcul...

Experimental Determination of Material Properties for Inflatable Aeroshell Structures

As part of a deployable aeroshell development effort, system design, materials evaluation, and analysis methods are under investigation. One specific objective is to validate finite element analysis techniques used to predict the deformation and stress fields of aeroshell inflatable structures under aerodynamic loads. In this paper, we discuss the results of an experimental mechanics study cond...

Effect of Specimen History on Structure and In-Plane Permeability of Woven Fabrics

Before being processed into composites, reinforcement fabrics may undergo repeated involuntary deformation, the complete sequence of which is here referred to as specimen history. To mimic its effect, fabric specimens were subjected to sequences of defined shear operations. For single fabric layers with unconstrained thickness, quantitative evaluation of photographic image data indicated that r...
