Stress analysis of filament-wound composite cylinders under combined internal pressure and thermal loading

Abstract

An analytical solution is performed using stress function approach for multi-layered filament-wound composite cylinders subjected to combined internal pressure and thermal loading. It is assumed that there is a liquid or gas of various temperatures in the cylinders. The effects of the wind angle variation through the radial section of the cylinders are also investigated. Thus, the layers are oriented symmetrically and antisymmetrically for (0790°), (307-30°), (45745°) and (607-60°) orientations. A computer program is developed to conduct stress and deformation analyses of composite cylinder with different winding angle. All the integration constants are found from the radial stress and displacement in the normal direction of layers.
