Abstract:

A comparison is made of the stress-strain response of a fabric in uniaxial stress and three loading conditions in biaxial stress. The results of the stress-strain tests were also compared with strain measurements made on a full-size tent. The results of the biaxial tests were found in better agreement with the stress-strain response in the full-size tent than the uniaxial tests. A suggestion is made for the development of a theory for predicting the biaxial stress-strain behavior of a fabric. This development will include the selection of a governing equation for the perfectly elastic state and finding the expressions needed to define the variables of the equation for a nonelastic material.
