Figure 7: S–N curves of S460NL steel under different corrosion conditions: (a–e) Experimental fatigue data with Weibull statistical fits (5%, 50%, and 95%) obtained using the Castillo–Canteli model. (f) Combined diagram showing all experimental fatigue failure data points for direct comparison between corrosion exposure conditions.

Figure 8. A set of photographs of fracture surfaces of steel specimens for the region of approximately 40,000 cycles. Fatigue fracture analysis Photographs of fracture surfaces of broken specimens were taken on an Olympus DXS 1000 digital microscope.
