Rayonnement acoustique de coques élastiques étudié par des méthodes intégrales

Abstract
A surface Helmholtz integral system is used for obtaining the solution of the exterior steady-state acoustic radiation problem for an elastic shell. It leads to the solution of a system of eight coupled integral equations governing two pressions, three components of the displacement vector on the exterior surface of the shell and three components of the displacement vector on its interior surface. The numerical method used to compute these pressions and components is tested on the case of a spherical shell in a radial field.
