Double-wall structures are widely used in noise control due to their superiority over single-leaf structures in providing better acoustic insulation. Typical examples include double glazed windows, fuselage of airplanes, vehicles, etc. In this context, we are interested in experimental and numerical study of the vibro-acoustic behavior of double-wall sandwich panels with viscoelastic core coupled to an acoustic enclosure. A finite element formulation is derived from a variational principle involving structural displacement and acoustic pressure in the fluid cavity. Since the elasticity modulus of the viscoelastic core is complex and frequency dependent, this formulation is complex and nonlinear. Therefore, the direct solution of this proble...
