Structural Response of Unstiffened Toroidal Shells

Abstract

Seven model epoxy toroidal shells were tested, and the results were compared with those from analytical solutions. The toroidal shells had a mean radius about the axis of revolution of 6 inches, a mean tube radius of 2 inches, and a mean shell thickness of 0.086 inch. The static elastic strain response of the epoxy models was in satisfactory agreement with that computed using a finite element analysis for axisymmetric shells. Critical buckling pressures for the models were approximately 85% of the analytical prediction, which was based on the mean dimensions.
