Spectra of computed fabric stress and deformation values due to a range of fictitious elastic constants obtained from different established determination procedures

Abstract

The aim of the present paper is to present ways how lower and upper limits for the range of possible fictitious elastic constants (tensile stiffness and Poisson’s ratio) can be determined for one fabric material on the basis of different established test and determination procedures. In the structural analysis this range of fictitious elastic constants results in a spectrum of computed stress and deformation values for one and the same structure and load case. The possible range of structural analysis results due to that variety of possible stiffness parameters is demonstrated for one exemplary membrane structure with different magnitudes of curvature.
