A mixed finite element method is briefly described to investigate the dynamic transient analysis of a flexible structure-water interaction system excited by pressure water waves. The fluid is assumed compressible and the mathematical model allows the inclusion of acoustical, structural and fluid (e.g., wave) interaction mechanisms. To illustrate the approach, a two dimensional model of a ship-water interaction system excited by a sinusoidal or a triangular shaped pressure wave is examined. These results are compared with those derived from two approximation methods. That is, the one neglects the compressibility of water but retains flexibility of the structure, the other assumes the structure rigid and static, the fluid compressible and the distributed dynamic pressure on the wetted surface of the structure calculated. Now treating the structure as flexible, the dynamic response of this structure is evaluated using the previously determined dynamic pressure as excitation. This simple comparison confirms that the contribution from the couples fluid-structure interaction analysis is a significant factor in determining responses.
