Abstract
Out-of-plane buckling can be observed when a piece of woven fabric is subje cted to a uniaxial tension along a direction which is not aligned with the warp or weft direction. Similar buckling does not occur either in the paper or thin fabric-reinforced composite plates. We attribute this difference t o a unique feature of fabric, namely that the fabric has a micro-weaving st ructure and fibres in fabric can slide almost freely unlike those in paper or fabric-reinforced composites. In the first part of this paper, we propos e a micromechanical model which takes into account this unique feature and modifies the traditional orthotropic continuum model by adding an extra com pressive stress field. In the second part, a linear buckling analysis is co nducted with the aid of both the traditional orthotropic continuum model an d our micromechanical model. We show that the above-mentioned buckling phen omenon is predicted by our micromechanical model and not by the traditional model. (C) 2000 Elsevier Science Ltd. Ail rights reserved.
