Abstract
Various methods of calculating the natural frequencies of flat rectangular cantilever plates are discussed, and it is shown both analytically and experimentally that relatively simple expressions based on technical beam theory give good results even for high order modes. Experimental results indicate that the mode shapes of plates of non-uniform thickness have modes so complex that a great many terms should be used in any vibration analysis, whether finite difference or Rayleigh-Ritz.
