了解涂层机织物的复杂性能对于设计最先进的织物结构至关重要。织物性能通常使用基于平面应力假设的弹性常数来定义。本文考虑了两种新的方法来表示织物响应：（i）使用样条函数来定义响应面，（ii）使用应力-应变均值和差函数（由Day提出[IASS研讨会论文集：壳，膜和空间框架2（1986）17]。这两种技术都提供了应力和应变之间的直接相关性，消除了平面应力的假设。提出了广泛的双轴织物测试，以评估这些方法的有效性，并扩大其使用。(C)2004 Civil-Comp Ltd.和Elsevier Ltd.保留所有权利。
An understanding of the complex behaviour of coated woven fabrics is vital for the design of state-of-the-art fabric structures. Fabric behaviour is typically defined using elastic constants based on plane stress assumptions. This paper considers two new methods of representing fabric response: (i) use of spline functions to define response surfaces, (ii) use of stress-strain mean and difference functions (proposed by Day [IASS symposium proceedings: shells, membranes and space frames 2 (1986) 17]. Both techniques provide direct correlation between stresses and strains, eliminating the assumption of plane stress. Extensive biaxial fabric testing is proposed to assess the validity of these approaches and extend their use. (C) 2004 Civil-Comp Ltd. and Elsevier Ltd. All rights reserved.
