Aerospace structures are often subjected to a broad spectrum of mechanical and/or aerodynamic excitations and, therefore, there is a need to develop techniques that is applicable for the resolution of vibroacoustic systems over the entire frequency spectrum. A substructure-based modeling technique that is applicable at all frequencies is developed and applied for the solution of complex dynamic systems. This method does not require traditional meshing, computationally very efficient, and allows for rational modeling of manufacturing variability.
