摘要：
A modal reduction method to solve the elastoacoustic vibration problem is analyzed. A two-dimensional coupled fluid-solid system is considered; the solid is described by displacement variables, whereas displacement potential is used for the fluid. A particular mode synthesis leading to a symmetric eigenvalue problem is introduced. Error estimates are provided and numerical experiments exhibiting the good performance of the method are reported.
