Abstract :
[en] Part 1 : The finite element formulation for fluid-structure problems - To the best of our knowledge, the first purely lagrangian formulation was proposed by Debongnie. At this time, even though natural, this idea as well as the notion of displacement potential led to some surprises. Thes rationalizing efforts led to the final formulation of the corrected Tong's formulation in 1978 and to the corresponding formulation for the compressible case in 1984. Similar results were obtained by Morand in 1987. Here, contrarily to our preceeding papers, we present the formulation from a local point of view instead of a variational one. PART 2 : On the representation of rigid body modes with the SAMCEF formulation for hydroelastic problems - The question to see wether the SAMCEF formulation of hydroelastic problems respects the rigid body modes is often raised. It appear very often that some of the rotational rigid body modes are lost for the fre-free problem. The present report tries to give a better understanding of this problem. PART 3 - Dynamic analysis of fluid-structure problems : results.
