Vibro-acoustic analysis of the acoustic-structure interaction of flexible structure due to acoustic excitation

Abstract

The application of BE–FE acoustic-structure interaction on a structure subject to acoustic load is elaborated using the boundary element–finite element acoustic structural coupling and the utilization of the computational scheme developed earlier. The plausibility of the numerical treatment is investigated and validated through application to generic cases. The analysis carried out in the work is intended to serve as a baseline in the analysis of acoustic structure interaction for lightweight structures. Results obtained thus far exhibit the robustness of the method developed.
