| Abstract: | Purpose – The purpose of this paper is to present the extension of plane wave based method. Design/methodology/approach – The mixed functional are discretized using enriched finite elements. The fluid is discretized by enriched acoustic element, the structure by enriched structural finite element and the interface fluid-structure by fluid-structure interaction element. Findings – Results obtained show the potentialities of the proposed method to solve a much larger class of wave problems in mid- and high-frequency ranges. Originality/value – The plane wave based method has previously been applied successfully to finite element and boundary element models for the Helmholtz equation and elastodynamic problems. This paper describes the extension of this method to the vibro-acoustic problem. |
