HYBRID METHOD FOR DETERMINING FATIGUE CHARACTERISTIC IN HIGH CYCLE LIFE
Abstract eng: The paper presents hybrid method for determine fatigue S-N curve in limited life region. To invent this method, gamma distribution of slope coefficient fatigue characteristics has been estimated. From this distribution was proposed value of slope S-N curve as mode of distribution m slope for smooth and notched specimen. To verify this approach, fatigue test of smooth and notched specimen of 42CrMo4 and C45+C steel has been carried out. Qualitative verification has occurred that proposed method get better results for notched specimen and worse for smooth specimen.
