• This paper presents eigenvalue, eigenvector and frequency response analysis techniques based on FEM for symmetrically laminated composite plates by using stand-alone desktop microcomputers. In order to realize these dynamic analyses on a microcomputer, a technique has been proposed to substitute a symmetrically laminated orthotropic plate in a single anisotropic plate model. By using this technique, 12 d.o.f. rectangular and 9 d.o.f. triangular finite elements have been formulated. A subspace iteration algorithm is used for the eigenvalue and eigenvector analyses. A modal analysis effective for this particular problem has been developed to calculate frequency response functions using the results of the eigenvalue analysis. Furthermore, pre- and postprocessor for eigenvalue analyses have been conducted. A vibration test using CFRP (carbon fiber-reinforced plastics) symmetrically laminated composite plates as test pieces is performed to prove the effectiveness of the method. Study shows that this dynamic analysis technique could be of practical use and the proposed eigenvalue analysis technique could be effective for the plates whereby not only a wide range of fiber angles but aldo a dynamic coupling effect between bending and torsion forces are taken into consideration.
