The discussion will be centered on the primal-dual dynamic aspects of this interaction which have been, only for the dual approach, deeply analyzed by B. Fraeijs de Veubeke and M. Geradin and then for structure-structure interaction, in static, by M. Gurtin. This will lead to discuss the appropriate variational formulations of the boundary value equations for incompressible liquids with a zero pressure free surface approximation then with the effect of compressibility. The gravity effects will be then recalled for further open investigations. 000013638 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000013638 653__ $$a 000013638 7112_ $$aCOMPDYN 2011 - 3rd International Thematic Conference$$cIsland of Corfu (GR)$$d2011-05-25 / 2011-05-28$$gCOMPDYN2011 000013638 720__ $$aOhayon, R. 000013638 8560_ $$ffischerc@itam.cas.cz 000013638 8564_ $$s7655$$uhttps://invenio.itam.cas.cz/record/13638/files/418.pdf$$yOriginal version of the author's contribution as presented on CD, section: MS 07 Computational Methods for Interface Problems. 000013638 962__ $$r13401 000013638 980__ $$aPAPER
