An efficient method of fluid–structure coupling in the dynamic analysis of structures

Abstract

Abstract A method of fluid‐structure connection is presented for solutions which mainly involve the calculation of the dynamic response of structures by using the method of modal analysis. This connection method is based upon finite element structural and fluid representation and is efficiently employed when used with the inverse iteration procedure for eigenvalue, eigenvector evaluation. The inverse iteration procedure is described in conjunction with the connection method. Also a method of non‐linear structural analysis and a method of frequency domain analysis are discussed with reference to the presented fluid‐structure connection procedure. Applications are considered for both model and prototype situations. Efficient use of the mini computer for solving dynamic problems by the proposed method is also considered.
