A Contribution to the Theory of Pressure Stabilized Structures

Abstract

A large-deformation analysis is presented for an element of a flexible inflatable plate consisting of an array of contiguous tubes. The element is represented by a transversely-loaded pressurized cylindrical chamber of indefinite length having two flat sides connected by flexible but inextensible membranes. The behavior of the cylindrical element is described for the complete range of deformation for the case of lateral compression, shear, or rolling loads, and a method is described for obtaining a graphical solution for the shape of the cross section under any given combination of loads. It was found that under certain conditions large compressive deformations give rise to geometrical instabilities, or conditions of negative spring rate.
