Membrane and Edge Effect Solutions of Filament-Wound Shells of Revolution.

Abstract

A method for analyzing stresses and displacements in filament wound shells of revolution is presented. This method of analysis is based on the membrane theory of shells but incorporates the edge effect theory to predict a more realistic behavior in the vicinity of polar openings. In addition, because it includes the contribution of the matrix, the present membrane theory is more accurate for the analysis of shells under nondestructive operating loads than is the so-called netting analysis which considers the filaments to be the only load carrying members. The membrane theory is also modified to give accurate solutions in the shallow region of composite shells and indicates significant bending stresses due to orthotropy and the shape of the meridian. While these stresses are localized near the apex in thin shells, they may extend well down along the meridian in thick shells.
