Nonlinear dynamical analysis for coupled fluid-structure systems

Abstract : The present research concerns the numerical dynamical analysis in elasto-acoustics, taking into account the geometrical non-linearities induced by the large displacements/deformations of the structure and assuming the internal acoustic fluid occupying an internal cavity coupled to the structure to remain in a linear range of vibration. More particularly, the modeling includes sloshing and capillarity effects on the free surface. A numerical application is presented.
