Analysis of stress–strain of architect woven fabric strength under biaxial extensions

Architectural fabric, or tensile fabric, structural fabric has become popular over the last decades. The structural fabric is used for shading public areas such as airport, boat docks, sport areas, public bus stops, and car parking. The most important advantages of the architectural fabric structure are low weight and more economical designs. In this research, three different fabric materials were studied to investigate the strain and stress in the fabric during time of using in the shading. The present work focuses on 2D biaxial orthogonal woven structure, among which plain weave is the distinct category. 2D means that the woven fabric features only in-plane reinforcing properties. Biaxial means that yarns are aligned along two directions: the warp and weft directions. Orthogonal means that the warp and weft yarns are laid down at 90° with respect to each other. The present work is aimed at developing a theoretical approach for prediction of fabric strain–stress relation based on the results achieved by experimental studies.
