✦ Synopsis

Using the perturbation method, the non-linear exterior fluid-structure interaction problem is separated into first-and second-order problems. With the finite element method for the structure and the finite-infinite element method for the fluid, we obtain a first-order coupled matrix system and a second-order coupled matrix system. By determining the frequencies of resonance of the structure, comparison of numerical results for a vertical cylinder and a horizontal floating cylinder shows the validity of the presented method for the resolution of three-dimensional exterior hydroelastic problems.
