Free vibrations of rectangular plates of exponentially varying thickness and with two free edges

This note is concerned with the transverse vibrations of the structural system described in the title. By using the classical plate theory and employing the Rayleigh-Ritz method and a finite element algorithmic procedure it is shown that the fundamental frequency coefficients obtained are in very go...

Description
Summary:This note is concerned with the transverse vibrations of the structural system described in the title. By using the classical plate theory and employing the Rayleigh-Ritz method and a finite element algorithmic procedure it is shown that the fundamental frequency coefficients obtained are in very good agreement. The fundamental frequency coefficient is determined using the optimized Rayleigh-Ritz method and the results are in good engineering agreement with the values obtained by means of a finite element code.
