This paper presents a validation case study for an Energy Finite Element Analysis (EFEA) formulation through comparison to test data. The EFEA comprises a simulation tool for computing the structural response of a complex structure and the amount of the radiated power. When the forcing function originates from an external flow, then the EFEA can be used for computing the vibration and the noise created due to the external flow excitation. In the past the EFEA has been used for computing the flow induced vibration for a large scale vehicle. The EFEA formulation presented in this paper can account for periodic stiffeners, for partial fluid loading effects on the outer part of the structure, and for internal compartments filled with heavy fluid. The new developments are validated by computing the vibration induced on a 1/8 scale structure representative of an advanced hull concept, and by comparing the simulation results to the test data.
