The finite element method and modal synthesis method for the fluid-structure acoustic vibration in 3D problems is introduced in this paper. The coupled finite element procedure is implemented for 2D and 3D structures based on the displacement formulations for continuum elastodynamics, and the FFT and modal synthesis analysis for actual physical model is conducted for comparison. The experimental results illustrate a practical performance of the eigenfrequency analysis for lower order modes of the fluid-structure nondestructive evaluations.
