摘要：

A symmetric finite element formulation for coupled acoustic vibration between a fluid and a structure is proposed. The fluid is described by the pressure and a displacement potential. The derivation of the finite element formulation is based on the weak solution of conservation of mass and linear momentum and on the Galerkin method. Numerical and analytical results show good agreement.
