The problem of elastic-fluid scattering is studied by combined integral equations for the exterior acoustic fluid and finite element methods for the elastic structure. These yield reduced problems over filile dommins. Tho woll-known dilficully with exterion integrnl equation methods at critical freq

An analysis of some nonconforming approximations of the Stokes problem is presented. The approximations are based on a strain-pressure variational formulation. In particular, a convergence and stability result for a method recently proposed by Bathe and Pantuso is provided.
In the last few years, the hybrid moment-merhod/finite-element-method (MM/FEM) approach has been wide& used to solve electromagnetic scatteringproblems. However, as is well known, this method faik at the resonance frequencies of a cauiv that is obtained by covering the surface of a scatterer with a
