FEM/BEM Coupling For Fluid-structure
Interaction Including Nonlinear Effects

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