The conventional boundary element method of analysis of noise problems inside cavities is inherently inaccurate at very low frequencies. This paper presents a new low frequency boundary element formulation, based upon a series solution in terms of the wavenumber. The new formulation gives accurate r

The interaction of acoustic waves with submerged structures remains one of the most di cult and challenging problems in underwater acoustics. Many techniques such as coupled Boundary Element (BE)=Finite Element (FE) or coupled InΓΏnite Element (IE)=Finite Element approximations have evolved. In the p
In the paper we have developed a new formulation for solution of structural-acoustic coupling problems by boundary elements using the multiple reciprocity method. It is assumed that the structure is composed of plate components and is excited by the external or the internal noise source. The efficie
This paper uses examples with exact solutions to demonstrate that boundary Bows with 8-node finite elements are more cost effectively calculated by extrapolation from the Barlow points than by direct sampling at the boundary. The boundary flows are used to calculate the mass balance, and the use of
