Plane Wave Scattering by an Elastic Sphere
Plane wave scattering by an elastic spherical shell is investigated in this demo example. A coupled BEM-FEM formulation is employed by Coustyx to model the feedback coupling between the surface acoustic pressure and the structure vibration. The FE model is further reduced using structure invacuo modes. Coustyx results are validated against the analytical series solution presented in Junger and Feit [1]. Excellent agreement between the two is observed.
