Dissipated Energy Measurements of Metal Material during High-cycle Fatigue Test Process

摘要：

　　In this paper,the high-cycle fatigue characterization of 316L stainless steel was studied based on dissipated energy measurement.At first,the dissipated energy per cycle was deduced from temperature field of specimen surface using an experimental mechanical method.Then,variations of dissipation energy per cycle were in-situ monitored during each high-cycle fatigue test under different stress levels.The results show that dissipated energy is mainly constant after the initial 5% cycles of total fatigue lifetime.Dissipated energy versus fatigue lifetime fitting curve shows the same pattern as the traditional stress versus fatigue lifetime curve.
