In this paper, a discrete method for analyzing the free vibration problem of laminated composite plates is proposed. By transforming the differential equations into integral equations and applying the numerical integration, the discrete solutions can be obtained. The characteristic equation of the free vibration is derived by applying the Green function which is obtained as a discrete solution of differential equations governing the flexural behavior of the laminated composite plates under the action of a concentrated load. By applying the characteristic equation, the behavior of the free vibration of the laminated composite plates can be analyzed efficiently without a calculation by trail and error method. The vibration frequencies and modes were obtained by this method, and compared with the other analytical results and experimental results by laser holography.
