Performance of a restrained-interface substructuring FE model for reduction of structural-acoustic problems with poroelastic damping
2011 (English)In: Computers & structures, ISSN 0045-7949, E-ISSN 1879-2243, Vol. 89, no 23-24, 2233-2248 p.Article in journal (Refereed) Published
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.
