Fatigue Behavior of Carbon Steel Components in High-Temperature Water Environments

Source

This paper describes the results of a combined experimental/analytical program on the fatigue initiation behavior of carbon steel components. Based on this study, several improvements in the fatigue analysis procedures are suggested: (1) a notch factor for local strains, (2) a mean stress factor, (3) improved fatigue strength reduction factor for butt welds, and (4) an environmental correction factor. It is shown that with the suggested fatigue analysis procedures, the fatigue design margins of the ASME Code will be maintained even with unusually severe local strain and mean stress.
