.... Cracking of the tube ends is a characteristic feature of thermal fatigue. Thermal fatigue damage typically exhibits numerous cracks and crazing. Damage due to thermal fatigue can be of the low-cycle or high-cycle type ( Ref 6.1 ). Drastic change in temperature causing thermal shock or a large...
