Abstract :
In this study, free vibrations of thick composite cylindrical and spherical shell panels with uniformly distributed attached masses were analyzed, using the standard Galerkin procedure. The stiffness effect of the distributed attached mass was taken into account for the first time, and the results were compared with well-known published results for which this effect was not considered. Various results for effects such as thickness, radii of curvature, and elasticity moduli are presented in this paper. Mass inertia of the distributed attached mass decreased the natural frequencies of the system, while the stiffness effect increased these values
