Abstract

Considering an accurate relationship between strains and displacements derived on the thin shell theory for twisted thin conical shells, a method for analyzing the vibrations of twisted conical shells made up of laminated composite materials is presented, in which the principle of virtual work for free vibrations and the Rayleigh-Ritz procedure with algebraic polynomials in two elements as displacements are adopted. The effects of the number of laminae, the fiber orientation, the twist, the taper ratio and the subtended angle on the vibration characteristics of cantilevered laminated composite conical shells are studied by the present method.
