Abstract
An energy finite element formulation for computing the high-frequency behavior of plate structures in contact with a dense fluid is presented. The heavy fluid loading effect is incorporated in the derivation of the governing differential equations and in the computation of the power transfer coefficients between plate members. The validity of the new formulation is demonstrated through comparison to an analytical solution and to results computed by conventional finite element models comprised by a large number of elements. The influence of the heavy fluid on the dynamic response of two marine structures is identified by comparing results computed with and without the effect of fluid loading. The impact of the heavy fluid loading on the computation of the power transfer coefficients is also identified. [Research supported by the Michigan Seagrant.]
