Laboratory and analytical fatigue studies were undertaken to assess the criticality of flaws found within several 63.5-mm-diameter communication tower eyebolts. Fatigue-fracture mechanics analyses provided fatigue life predictions which compared closely with subsequent fatigue experiments on the eyebolts subjected to particular load histories. Results of the study provided the basis for continued usage of many of the used eyebolts and gave specific guidelines on flaw size/location/criticality that were important in setting nondestructive inspection intervals and sensitivity limits.
