Vibrations of doubly cantilevered laminated-composite thin shallow shells
AbstractVibrations of laminated-composite thin shallow shells that are doubly cantilevered (i.e. with two adjacent edges clamped and the remaining free) are analyzed. The Ritz method, with algebraic polynomial displacement functions, is used. Convergence studies are made which demonstrate that reasonably accurate results are obtained by using 147 displacement terms for spherical, circular cylindrical, and hyperbolic paraboloidal shallow shells and 49 terms for plates. The effect of the material, fiber orientation, and curvature upon the frequencies is studied. The difference in behavior between these shells and those studied earlier (completely free, cantilevered, and simply supported) is outlined.
