A method is presented for the numerical study of the interaction of elastic bodies and acoustic fields. It is based on an integral equation technique wherein a sheet of acoustic sources and a sheet of forces are spread over the body surface. Their strengths are adjusted so that the boundary conditions are satisfied at the fluid‐solid interface. Because the calculation involves only a description of the body surface, it offers a more rapid numerical process than the more usual finite element calculations, where equations of motion must be developed for all points within the interior of the body as well.
