摘要: 对编织物受沿与其经线方向成任意角度θ(0<θ<90°)的单向拉伸时的屈曲进行了分析,得到了确定其屈曲方向角β的方程,给出了当θ=45°和θ=30°时确定屈曲方向角β的方程的解曲线.证明了当编织物受到沿非经向/非纬向的单向拉伸时,屈曲是可能的,得到了两种可能的屈曲模态(弯曲模态和拉伸模态)以及相应的屈曲条件.Zhang和Fu(2001)的结果为其结论的特例.

Abstract: The buckling of a fabric sheet subjected to a uniaxial tension in a direction making arbitrary angle,θ(0<θ<90°) say,with respect to that of warp is investigated.The equation to determine the buckling direction angle,B say,was obtained and,as illustration,the solution curves of the equation for θ=45° and θ=30° were plotted.It is shown that when the fabric sheet is subjected to tension in non-warp/ non-weft direction the out-of-plane buckling of fabric is possible,two buckling modes(flexural and extensional modes) and the both corresponding buckling conditions are obtained.The results given by Zhang and Fu(2001) are the special cases of this paper.
