The formulation of free vibration of orthotropic quadrilateral thick plates and composite laminates is developed in the context of p-version of the finite element method. The principle of dimensional reduction is used in the formulation to accurately model the three-dimensional behavior so that the geometrically two-dimensional character of the problem is maintained. This is done by defining the transverse and in-plane displacement functions in a product form at each lamina level. All nine elastic constants of orthotropy are taken into account. The computer program was developed using FORTRAN to calculate eigenvalues and eigenvectors. The accuracy of the results have been evaluated with reference to closed form analytical solutions and excellent agreement is noted.
