Résumé : The aim of this paper is to present a new finite element program (FLUSTRU) for fluid-structure interaction in a lagrangian formulation. The stiffness and damping matrices of the fluid are computed from the governing laws of the medium, i. e. the fluid is supposed to be viscous and compressible. The main problem stated by the lagrangian formulation of the fluid is the presence of spurious free-vibration modes (zero energy modes) in the fluid.
