Description of a S-N Curve.Fatigue properties of materials are often described using the fatigue limit or the S-N curve (fatigue curve,Wöhler curve).The S-N curve describes the relation between cyclic stress amplitude and number of cycles to failure.The figure below shows a typical S-N curve.On the horizontal axis the number of cycles to Fatigue - ASM Internationalsa =se 17 sm su x (Eq 14.6) wherex=1fortheGoodmanline,x=2forthe Gerber curve,su =sy for the Soderberg curve,and se is the fatigue limit for completely reversed bending.14.3 Low-Cycle Fatigue During cyclic loading within the elastic regime,stress and strain are directly related throughtheelasticmodulus.However,forcyclic 80 1045 Steel Fatigue Strain-Life Behavior of Carbon and Low-Alloy stainless steel test specimens in water environment 25 23.Experimental data and probability of crack initiation for Alloy 600 test specimens in air and water environments 25 24.Adjustment for mean stress effects and factors of 2 and 20 applied to best-fit S-N curves for carbon and low-alloy steels to obtain the ASME Code design fatigue curve
