Abstract:

Radiated acoustic pressure fields are obtained when two concentric free-flooded cylindrical shells of finite lengths are excited by a time-harmonic point force. Integral equations are formulated for the two elastic thin shells with simply supported boundary conditions at both ends. Near and far-field acoustic pressures are calculated and effects of acoustic coupling between two shells are discussed.
