Abstract

Finite element models are presented for the prediction of the non-linear response of fluid structure systems exposed to transient dynamic loading. Both geometrical and material non-linearities are considered. An arbitrary Langrangian - Eulerian kinematical description of the fluid domain is adopted on which the grid points can be displaced independently of the fluid motion. This formulation leads to an easy and accurate treatment of fluid structure interfaces and permits significant fluid sloshing and swirling to occur without producing excessive distortions of the computational mesh. Some aspects of the structural response in the frequent case of axisymmetric conditions are then examined. Several applications are presented to illustrate the potential of the proposed modelling procedures.
