Optimization of characteristics of porous materials based on a modal synthesis method [PDF]
European Journal of Mechanics - A/Solids, 2009 Complex structures used in the automotive industry often include porous materials, in order to reduce the noise in acoustic cavities. The method proposed in this paper aims at optimizing the characteristics of these porous materials using modal criteria based on the modal analysis of the structure.

A modal synthesis method for the elastoacoustic vibration problem [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2002 A modal synthesis 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 modal synthesis leading to a symmetric eigenvalue problem is introduced.
