✦ Synopsis
A theoretical method is developed to investigate the e!ects of ring sti!eners on vibration characteristics and transient responses for the ring-sti!ened composite cylindrical shells subjected to the step pulse loading. Love's thin shell theory combined with the discrete sti!ener theory to consider the ring sti!ening e!ect is adopted to formulate the theoretical model. The ring sti!eners are laminated with a composite material and have a uniform rectangular cross-section. The Rayleigh}Ritz procedure is applied to obtain the frequency equation. The modal analysis technique is used to develop the analytical solutions of the transient response. The analysis is based on an expansion of the loads, displacements in the double Fourier series that satisfy the boundary conditions. The e!ect of sti!ener's eccentricity, number, size, and position on transient response of the shells is examined. The theoretical results are veri"ed by comparison with FEM results.
