摘要：
This article deals with the solution of the scattering of a plane acoustic wave by an elastic structure. This solution consists in the coupling a finite element code (ATILA) and a boundary element code (EQI). The first one enables the modeling of the vibrating structure and the second one the modeling of propagating waves in the infinite fluid medium surrounding the body. The coupling method is described and successfully applied to the scattering by an elastic spherical shell and a cylinder with hemispherical endcaps.
