Figure 2-3. Typical fatigue cracking of riveted member

Therefore, fatigue cracks would more likely be detected long before the load-carrying capacity of the riveted
member is exhausted.
d. Fatigue strength of corroded members. For severely corroded members where corrosion notching has
occurred, Category E or E' curves and the corresponding fatigue limits have been suggested for cases. When
corrosion is severe and notching occurs, a fatigue crack may initiate from the corroded region as shown in
Figure 2-5. In cases where corrosion has resulted in loss of more than 20 percent of the cross section, the
corresponding increase in stress should also be considered.
