FATIGUE LIMIT PREDICTION OF AISI4140 STEEL WITH COMPRESSIVE RESIDUAL STRESS CONSIDERING THE LOCAL YIELDING OF COMPRESSIVE RESIDUAL STRESS LAYER

The effect of compressive residual stress on the fatigue limit was investigated using fatigue tests on specimens with and without compressive residual stress. The results demonstrated that the fatigue limit of AISI4140 steel with compressive residual stress can be predicted using the fatigue limit diagram, considering the local yielding of the compressive residual stress layer.
