This paper presents an efficient FEM eigenvalue analysis technique for symmetrically laminated composite plates by using a personal computer. In order to realize the analysis on a personal computer, a 12 d. o. f. ACM element considering the anisotropic behavior of symmetrically laminated composite is formulated and a subspace iteration algorithm is used for the analysis. A shaking test using CFRP symmetrically laminated composite plates is performed to prove the effectiveness of the method. It has been shown from the study that the proposed technique could be of practical use for plates with a wide variety of fiber angle and dynamic coupling between bending and torsion.
