In this paper, the boundary element method is coupled with the finite element method to accurately model sound–structure interaction of a composite panel resting on an acoustic cavity. First, the approach is validated by comparing the numerical solutions with known analytical and experimental results for isotropic panels. However, for composite panels, exact solutions are difficult or impossible to compute. Also, until today, very little effort has been made to obtain experimental results for composite panels undergoing sound–structure interaction. As the first step toward exploring this area of sound–structure interaction, this study offers numerical results on an acoustic cavity-backed composite panel by harnessing the strengths of the coupled BEM–FEM technique. The results indicate that the transmission loss values for composite panels are very sensitive to the lamination angle of the fibers in the different layers of the composite panel.Read More
