Abstract : The interaction of waves traveling in an acoustic medium with an elastic obstacle (or vice versa) is studied by a formulation which has been useful in previous acoustic and representation of wave problems and has the advantage of involving only boundary (i.e., interface) values of the unknowns thus reducing the dimensionality of the problem. A simple example of plane wave scattering is included as an illustration for both time harmonic and transient cases. (Author)
