Table 29.8 gives values of a. The stress-concentration factor K f may be applied to the nominal stress 0 as K f 0 as an augmentation of stress (preferred) or as a strength reduction factor ke = 1/K f (sometimes convenient). The finite life stress-concentration factor for steel for N cycles is obtained from the notch sensitivities (q)103 and (q)106. For 103 cycles,

There is some evidence that K f does not exceed 4 for Q&T steels and 3 for annealed steels [29.11]. Figure 29.10 shows scatter bands, and Fig. 29.11 relates notch radius to notch sensitivity.
29.3.6 Miscellaneous-Effects Modification Factor ke There are other effects in addition to surface texture, size loading, and temperature that influence fatigue strength. These other effects are grouped together because their influences are not always present, and are not well understood quantitatively in any comprehensive way. They are largely detrimental (ke < 1), and consequently cannot be ignored. For each effect present, the designer must make an estimate of the magnitude and probable uncertainty of ke. Such effects include
Introduction of complete stress fields due to press or shrink fits, hydraulic pressure, and the like Unintentional residual stresses that result from grinding or heat treatment and intentional residual stresses that result from shot peening or rolling of fillets Unintended coatings, usually corrosion products, and intentional coatings, such as plating, paint, and chemical sheaths Case hardening for wear resistance by processes such as carburization, nitriding, tuftriding, and flame and induction hardening Decarburizing of surface material during processing
