Abstract
Presents the natural frequencies and vibration mode shapes of curved panels with variable thickness by using the transfer matrix method. The transfer matrix is derived from the non-linear differential equations for the curved panels with variable thickness, by using the Fourier series expansions in the longitudinal direction and then applying a numerical integration in the circumferential direction. Investigates the accuracy and convergence characteristics of this method and examines the influences of cross-section thickness variation on the natural frequencies and mode shapes of curved panels with variable thickness.
