DYNAMIC RESPONSE OF IMMERSED STRUCTURES IN BOUNDED DOMAIN WITH GRAVITY WAVES

摘要

This work concerns the study of the dynamic behavior of tanks containing fluid.Finite elements are used for modeling both the elastic walls of the tank and the fluid domain. The influence of the free surface condition on the behavior of the coupled problem is studied and the gravity effect is taken into account.The results are compared with those obtained in the following particular situations :-sloshing with rigid walls,-elastic walls with an equipotential free surface condition, and the comparisons are made for various heights of the fluid.
