Abstract
Recent research on the energy finite element method (EFEM) has focused on the development of structural–acoustic coupled capability. This formulation has been developed successfully in terms of radiation efficiency. The approach has been implemented into the finite element method and successfully verified against experimental results for an enclosure with one flexible wall. Calculation of the sensitivity of the response to various parameters of the model is reasonably straightforward in the EFEM formulation. This capability was used for system identification for the experimental verification problem and for understanding the dominant mechanisms which govern the structural acoustic response at high frequency for both acoustical and mechanical excitation of the enclosure problem.
