ANALYSIS OF FILAMENT-WOUND PRESSURE VESSELS.
Abstract
This report gives a systematic and comprehensive presentation of methods for analyzing stresses and deformation in filament-wound pressure vessels. The stress-strain relations for elastically anisotropic materials, in general, and for the particular anisotropy displayed by filament-wound shell structures are discussed as essential fundamental premises to the analyses developed. Many important applications of the general theory to laminated structural elements have been developed. Recently, cylindrical pressure vessels and closure domes have been investigated under the assumption that the filaments are the only loadcarrying elements in the composite structure. This socalled netting analysis approach is investigated and re-formulated as the limiting case of a more general analysis which includes contributions of both the filaments and the resinous matrix to the strength of the structure. The latter approach is, of course, indispensable for the analysis of the bending and shearing stresses caused by discontinuity (or edge) effects. Analysis of these stresses is developed in the remaining sections of this report.
