"A Galerkin BEM for Acoustic Radiation and Scattering";
ZAMM - Zeitschrift für Angewandte Mathematik und Mechanik,
A symmetric Galerkin formulation of the Boundary Element Method for acoustic radiation and scattering is presented. The basic integral equations for radiation and scattering of sound are derived for structures which may consist of a three-dimensional closed part and a thin-walled open part. For the numerical solution of these integral equations a Galerkin-type numerical solution scheme is proposed. The numerical study contains a comparison of measured and computed results for a structure consisting of a three-dimensional closed part and a thin-walled open part.
