摘要：

In steam generator of nuclear power plant, flow induced vibration in a U-tube bundle could cause wear and fatigue failure. This vibration causes fretting-wear between the supporting plates and tubes by generating infinitesimal friction. In this study, a substructure method is developed for three dimensional finite element models of fretting wear problems and its feasibility is also verified. The substructure method can reduce large amount of computation time required by conventional finite element analysis.
