Study on free vibration behavior of composite inner/outer ring-stiffened cylindrical shells

This research presents Dynamic Stiffness formulations for studying dynamic behavior of composite inner/outer ring-stiffened cylindrical shells. The continuous elements investigated in this paper are cylindrical and ring elements. Base on dynamic stiffness matrix of the above elements, an assembling procedure is proposed to solve the problem of complex composite inner/outer ring-stiffened cylindrical shells.
