摘要

Tension structures continue to be of increasing importance to military applications requiring both minimum weight, small packing volumes, and enhanced deployment operations. Present design methods for inflated fabric structures, however, are not well established. Analytical tools required to efficiently design these structures lag behind those for conventional structures and materials-partly because of nonlinearities resulting from changes in fabric architecture upon loading. In particular, constitutive relationships must be developed to establish the pressure-dependence and coupling effects of biaxial tension and shear loads. Through analysis and experiment, this study addresses the changes in fabric architecture and, more specifically, the combined effects of biaxial tension, shear, and crimp interchange on the global behavior of woven fabrics. A novel fixture for use in experimental testing of fabrics subjected to combined biaxial tension and shear loads is introduced in this report.
