FREE VIBRATION OF THICK COMPOSITE LAMINATES WITH CLAMPED EDGES USING CHARACTERISTIC ORTHOGONAL POLYNOMIALS IN RAYLEIGH-RITZ METHOD

Free vibration of composite laminated thick plates with clamped edges is investigated by employing a set of characteristic orthogonal polynomials in Rayleigh-Ritz method.The solutions in this paper are compared with the results existing in the literature,and good agreement is obtained.The effects of various parameters and boundary conditions of laminated plates on the fundamental frequencies are studied.
