A numerical method to analyze the free vibration of a pre-twisted cantilever plate is presented in this paper. The method proposed is based on the Rayleigh-Ritz procedure. Frequency parameters and more shapes of vibration for typical pre-twisted plates are computed and compared with results obtained by other investigators. The comparison shows that the method proposed is useful for analyzing the free vibration of pre-twisted cantilever plates. Then, the effect of pre-twist and the aspect ratio of plates on the free vibration is investigated.
