Analysis and Design Of Composite Pressure Vessel using Lamination Theory and Shell Theory

Abstract

Strength of a Nation is dependent on how advanced material is used for designing structure. In this paper simplified approach of design of composite pressure vessel using lamination theory and shell theory is presented. Two dimensional lamination theories are able to handle orthotropic material in case of composite. Lamination theory is used to calculate the stresses and strains in each layer of laminate. Shell theory is used for calculation of curvature effect in case of pressure vessel. Variation of stresses and strains across thickness of laminate are plotted. A method to optimize the winding angle in case of filament winding layer is presented. Optimization method is useful for weight reduction of structure. Filament winding technology is well known manufacturing method for filament wound structure is presented in this paper.
