其他摘要：The dynamic behavior of structures in contact with fluids use to differ from such behavior in absence of the fluid. In this work, an implementation of Rayleigh Ritz in physical coordinates for modal analysis of tluid structure interaction of internal, incompressible, irrotational fluid is presented. Only a few simple cases are considered. The results show that the method is adequate for this kind of problems and applications to more complex cases are under development.
