An unconditionally stable algorithm is proposed for the dynamic analysis of incompressible fluid-filled systems. This approach decouples the fluid and structural effective stiffness matrices via a mixed finite element method. The two resulting matrices are shown to be symmetric and sparse and the semi-bandwidths of both matrices are small when they are compared to that of the traditional implicit method. Consequently, the potential saving in computer storage and cost is clearly significant. The comparisons of this numerical method with the traditional implicit method are also given.
