Vibraciones Transversales de una Placa Ortótropa con Bordes Elásticamente Restringidos contra Rotación y un Orificio Circular

Diana V. Bambill, Rubén D. De Ríos, Carlos A. Rossit, Patricio A. A. Laura


The present paper deals with the approximate determination of the fundamental frequency coefficient of the structure described in the title in the case where the edge of the hole is free. Polynomial coordinate functions and the Rayleigh-Ritz method are employed. Good agreement with: a) experimental resulte and b) finite element values, is obtained in the case of an isotropic, clamped, square plate previously studied in the technical literature.
