Abstract
A numerical method for analyzing free vibrations of composite laminated twisted cantilever thin plates is presented. The proposed method is based on the Rayleigh-Ritz procedure using algebraic polynomials as assumed displacement functions. The frequency parameters obtained are compared with previous theoretical results. Free vibrations of three-layer laminated (θ/-θ/θ) and four-layer laminated (θ/-θ/θ/-θ) plates are studied and the effect of fiber orientation and twist angle on the vibration characteristics of the plates is investigated.
