Vibrations of Rib-Stiffened Circular and Elliptical Plates [PDF]
The Journal of the Acoustical Society of America, 1968 This investigation deals with the determination of the fundamental frequency of vibration of simply supported and clamped rib-stiffened plates of elliptical boundary. It is assumed that the stiffeners are closely spaced and their height is moderate when compared with the thickness of the plate.
