A Theory and Applications of Filamentary Structures. Part 1: Theoretical Studies

Abstract

A general theory of filamentary structures consisting of monotropic membranes is presented. Applications to isotensoid pressure vessels with rotational symmetry demonstrate the use of the general theory. Particular attention is given to applications of filamentary design of variable-geometry expandable structures. An extension of the theory to pressurized filamentary structures subject to centrifugal loading and the special case of meridional winding patterns are presented in two Appendices. Physical interpretation of the resulting shapes and winding patterns leads to a discussion of the morphology of filament-wound pressure vessels. Design implications in terms of weight/volume/ pressure and volume/ surface-area relations are discussed. Directions of further investigations are indicated, involving studies of instability phenomena, development of filamentary textures other than those described by monotropic membranes, and design for concentrated-load-carrying pressure-stabilized structures.
