Formulation and Characterization of Fatigue Strength Diagrams of Notched Specimens Based on Equivalent Cyclic Stress Ratio,Attending Especially to Material Dependence and Notch Size Effects

摘要：

　　In the present paper,a fatigue strength diagram is formulated and characterized as a function of an equivalent cyclic stress ratio (named as REQ-ratio).The REQ-ratio is derived from a hypothesis of plastic adaptation that reflects micro-mechanical behavior of a fatigue slip band,and it was proposed as a corresponding parameter between cyclic stress-conditions of notched and un-notched specimens in the previous paper.
