MMPDS-01 31 January 2003 Figure 2.3.1.2.8(b). Best-fit S/N curves for notched, K t = 1.5, 4130 alloy <strong>steel</strong> sheet, normalized, longitudinal direction. Correlative Information for Figure 2.3.1.2.8(b) Product Form: Sheet, 0.075 inch thick Properties: TUS, ksi TYS, ksi Temp., EF 117 99 RT (unnotched) 123 -- RT (notched) K t 1.5 Specimen Details: Edge Notched, K t = 1.5 3.00 inches gross width 1.50 inches net width 0.76 inch notch radius Surface Condition: Reference: Electropolished 3.2.3.1.8(d) Test Parameters: Loading - Axial Frequency - 1100-1500 cpm Temperature - RT Environment - Air No. of Heats/Lots: Not specified Equivalent Stress Equations: Log N f = 7.94-2.01 log (S eq - 61.3) S eq = S max (1-R) 0.88 Std. Error of Estimate, Log (Life) = 0.27 Standard Deviation, Log (Life) = 0.67 R 2 = 84% Sample Size = 21 [Caution: The equivalent stress model may provide unrealistic life predictions for stress ratios beyond those represented above.] 2-32
