Abstract
A general method is proposed for the dynamic response analysis of fluid-structure systems. The method is based on the finite element discretization of the complete system assuming pressure to be the nodal unknown for the compressible fluid domain. All the matrices involved in the computation are made to be symmetrical and banded. Some approximations are suggested which result in great computational advantages with no significant loss of accuracy. The major computational efforts required for the analysis of the complete system is reduced to that for the independent analyses of the two subsystems. The effectiveness of the proposed method is demonstrated by solving some example problems.
