Title Formulae for Handcalculation of Deflection and Stress of Rectangular Coated Plain-Weave Fabric
Author Hirokazu Minami
Summary Taking advantage of a mechanics in the mutually supporting system of crossing warp and weft yarns in plain-weave fabric, a rectangular coated fabric was considered as a composite material of a principal membrane element having unit width including one yarn in the principal direction and the other orthogonal membrane elements also having unit width. Consequently, formulae for the approximate handcalculation of the deflection and stress were obtained. The formulae were verified by comparison on the central deflections calculated and measured on a flat square specimen subjected to lateral pressure. In conclusion we could consider that the formulae were adoptable to the practical approximate handcalculations in place of advanced computer analysis such as finite element method analysis.
