Finite element formulations of structural acoustics problems

This paper summarizes and reviews several finite element formulations used to solve structural acoustics and fluid-structure interaction problems. The fluid can be modeled using finite element formulations based on fluid pressure, displacement, velocity potential and displacement potential, each of which has advantages in different situations. In addition, finite element structural models can be coupled with either boundary element or infinite element fluid models. The formulations are applicable to a variety of applications, including acoustic cavity analyis, acoustic radiation and scattering from elastic structures vibrations of submerged structures, dynamics of fluid-filled piping systems, underwater shock analyis and transient acoustics.
