Finite Element Solution of Fluid-Structure Interaction Problems

Abstract

A finite element method for computing natural frequencies of a submerged structure is implemented using a structural analysis program to solve a sample problem. In this method, the structure and the surrounding fluid are represented by finite elements. Finite element solutions of the sample problem compare well with an analytic solution for both consistent and lumped formulations of the fluid-structure interaction effects.
