Abstract

This work deals with numerical computation of structural-acoustic applications including dissipative interfaces, in the context of structure-borne noise reduction. It focuses on the need to propose efficient solution strategies for costly finite element modelling. As such, a restrained-interface component mode synthesis is applied to the conservative parts of structural-acoustic applications. The method description being general and computational-oriented, it is straightforwardly applicable to a wide range of problems. The aim is to establish the efficiency as well as the limitations in the use of such a reduced model for harmonic solutions to dissipative structural-acoustic applications including 3D modelling of porous media.
