Various numerical procedures, which each have respective merits anddrawbacks, are available for the investigation of fluid-structure interaction problems. This paper concentrates on the coupling of the finite elementmethod, used to model the structure, and the boundaryelementmethod representing the fluid. Both methods are formulated in the timedomain and a special algorithm is developed to realize the coupling. In particular, nonlinear effects, such as material nonlinearities, large displacements or unilateral boundary conditions, may be taken into account in the structural model, while an infinite expansion of the fluid region is included in the boundaryelement formulation. Numerical examples exhibit the applicability of the new approach. It is observed that nonlinearities may have a considerable effect on the behavior of the fluid-structure system.
