Abstract
This paper deals with analysis of laminated composite barrel shells. Barrel shells are essentially cylindrical shells for which the meridional direction of the shell has some initial curvature. The curvature may be due to imperfection in manufacturing, or is a part of the design as is the case in barrel shells. The equations are developed for the general dynamic analysis of laminated barrel shells and can be reduced to the static analysis and the free vibration analysis. Natural frequencies are obtained for open and closed, isotropic and laminated barrel shells having shear diaphragm boundary conditions. For composite shells, the effects of curvature, thickness, and orthotropy ratios as well as the lamination sequence on the nondimensional natural frequency parameters are studied.
