摘要

This paper is devoted to the development of two finite elements for the study ofrninflatable structures made of double-layered fabric sheets submitted to highrnpressures. Large displacements and following forces are taken into account. The firstrnis an inflated beam element issued from the equilibrium finite element theory,rnbecause the analytical solution shows that the compliance of these double-layeredrnstructures is the sum of yarn and beam compliances. The second element is a plainrnstrain finite element built from a direct minimization of the total potential energy ofrnthe membrane elements. The numerical solution is obtained by solving directly thernoptimisation problem of the discretized structure. It is shown that these two elementsrnare able to give accurate solutions for fabric panels submitted to high pressure andrnbending loads. Comparisons with experimental results show the efficiency of theserntwo elements.
