FREE VIBRATIONS OF BEAMS OF BILINEARLY VARYING THICKNESS

Free vibrations of Bernoulli beams of bilinearly varying thickness are studied using: (a) the optimized Rayleigh-Ritz method, (b) the differential quadrature technique and (c) the finite element approach. It is shown that the fundamental frequencies of vibration of the structural elements as determined by the methodologies (a) and (c) are in excellent agreement while rather considerable discrepancies are found when using the differential quadrature technique. The values of the second and third natural frequency coefficients determined via the finite element method are also presented.
