Abstract

In this paper the numerical procedure based on a coupling the finite element formulation and the boundary element method is developed for the forced vibration analysis of shells of revolution partially filled with the fluid. We obtained numerical results for dynamic problems for the cylindrical and conical shells interacting with a liquid both in the absence of the disturbing force (free vibrations) and with given external dynamic effects (forced vibrations). For cylindrical shell we investigate the influence of different filling levels. And for conical shell the research was carried out concerned with varying cone slope and its influence on displacements.
Keywords free vibrations, forced vibrations, fluid-structure interaction, FEM and BEM
