experimental results with the S-N curve predicted based on the sc S-N prediction model. In particular, the test frequency significantly affected the RB bending fatigue life. Therefore, when new S-N data is obtained using the RB fatigue testing machine or the database of RB fatigue strength obtained in the past is utilized for fatigue design, care must be taken regarding the test conditions, especially the test frequency.
