摘要：In the present work, the implementation of the Rayleigh-Ritz method in physical coordinates is presented for the modal analysis of rectangular plates or combinations of rectangular plates. The implementation procedure is described, several examples are presented and results compared with alternative methods. The results analyzed show that the method is competitive with alternative techniques and shows a greay potential to deal with large structures.
