A micro-mechanical model of woven fabric and its application to the analysis of buckling under uniaxial tension. Part 2: buckling analysis

With the aid of the micro-mechanical model far woven fabric proposed in Part 1, we analyse the buckling of a fabric sheet when it is subjected to uniaxial tension. To simplify analysis we focus our attention on the case when the inclination angle between the direction of uniaxial tension and that of warp is either zero or 45 degrees. We first show that under the traditional orthotropic continuum model out-of-plane buckling of fabric is not possible whether the inclination angle is zero or 45 degrees. Using our new model, we show that out-of-plane buckling is not possible when the inclination angle is zero but is possible when the inclination angle is 45 degrees. Both results agree with our experimental results. (C) 2000 Elsevier Science Ltd. All rights reserved.
