The influence of fatigue failure characteristics on oil drill pipe joints

The influence of fatigue failure characteristics on oil drill pipe joints:
1. Fatigue crack initiation: Under cyclic loading, stress concentration areas or material defects in drill pipe joints are prone to fatigue crack initiation. These cracks will gradually propagate as the cyclic load continues to act.
2. Fatigue fracture: When fatigue cracks propagate to a certain extent, the drill pipe joint will experience fracture failure. This type of fracture is usually sudden and unpredictable, posing a serious threat to the safety and efficiency of drilling operations.
