FATIGUE-CRACK GROWTH IN PERSPECTIVE

The similarities between the crack-growth vs stress-intensity range relationship, and the conventional stress vs number of cycles to failure relationship are discussed. The results of published fatigue-crack growth studies are analyzed in terms of broad spectrum fatigue life and limiting conditions. It is concluded that fatigue-crack growth rate is not a simple power function of stress-intensity-factor range as some contend. Furthermore, the scope of fatigue-crack growth studies must be greatly expanded to cover the majority of fatigue failures that occur in service.
