Abstract

The advanced formulation of the boundary integral equations method is suggested for forced vibrations of an elastic structure immersed in and/or filled by compressible unviscous liquid. A structure is supposed to consist of plates and parts of spherical and cylindrical shells. The classical boundary equation related to contact acoustic pressure is modified by substitution of Somigliana's type formulae for normal displacements on each part of a structure. As a result, the second-level equation constitutes the connection among contact acoustic pressure, driving loads and boundary displacements and forces on each part of a structure.
