摘要：
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.
