1. How does the poster know it’s fatigue fracture 2? You don’t even say where the fracture occurred, or what the medium or other factors are – how are we supposed to respond? Do we have to consider it from the perspective of fatigue fracture? Apart from fatigue caused by vibration, what other factors can cause fatigue in that device? If it’s pressure or temperature, then problems will definitely arise first in the tube sheet.
