Abstract: The
resonance sound radiation from submerged infinite elastic
cylindrical shell, excited by internal harmonic line force, is
investigated. The shell radiation power is presented in terms of
resonant modal radiation derived from resonance radiation theory
(RRT). The resonance radiation formulae are derived from
classical Rayleigh normal mode solution, which are useful for
understanding the mechanism of sound radiation from submerged
shells. As an example, numerical calculation of a thin steel
cylindrical shell is done by using these two methods. It seems
that the results of RRT solutions are in good agreement with
that of Rayleigh normal mode solutions.
