This paper describes an efficient strong coupling method for fluid-structure interaction based on the explicit method for structure and the semi-implicit method for fluid. The solution process of fluid-structure interation system is divided into that of fluid and structure, which is independent to each other except data transfer of the fluid-structure interface. Some existing codes with small modification can be utilized to realize the above two solution processes. Note that the time increment is restricted by the Courant's and diffusive number conditions. The method is applied to solve a loaded cantilever in a flow channel under some conditions. Through the numerical results, characteristics of the method are compared to those of a strong coupling and a weak coupling method.
