Transient Analysis of Fluid-Coupled Elastic Shell Systems Using Fluid Finite Elements.

Abstract

The eight node, first order hexahedron finite element in the NONSAP structural analysis program has been modified to simulate an ideal compressible fluid. This element, based on the displacement formulation, is then incorporated into the STAGS finite element program. The effectiveness of this fluid finite element is demonstrated by computing the transient response of two submerged fluid-coupled cylindrical elastic shells impinged upon by a transversely incident plane pressure pulse and comparing the results to an analytical solution.
