Approximate methods for the determination of the natural frequencies of stiffened and curved plates
Abstract
Simple approximate formulae for the natural frequencies of the modes of vibration of certain stiffened and singly curved panel structures with in-plane stresses are determined. The analyses, which are partly empirical and which partly rely on simple assumptions, are aimed at presenting reasonably accurate solutions that will permit rapid computation. Calculated results using these formulae agree favourably with figures obtained by more accurate methods.
