Vibration analysis of curved panels with variable thickness

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.
