Vibraciones de una Placa Ortótropa Cantilever: Solución Mediante el Método de Rayleigh-Ritz Optimizado y Comparación con Elementos Finitos

Abstract

of rectangular, cantilever, orthotropic plates is determined by means of the optimized Rayleigh-Ritz method using a pseudo-Fourier expansion of the type:
sin2 (π.x/γ2.a) cos(π.y/γ1.b) γ1, γ2 >1
The fundamental frequency coefficient is optimized with the respect to the r's. It is shown that the results are in good agreement with the predictions of a finite element code.
