1. Clarifications and terminology
Fatigue refers to the progressive damage caused to structural details by fluctuating or repeated stresses, leading to cracking and eventual failure.
-
All structural details susceptible to fatigue must be identified and fatigue-tested.
In the case of a smooth part, cracking can originate from microscopic grain-scale defects, or from edge defects caused by flame cutting or drilling, for example.
In the case of welded constructions, there are always defects due to the weld: in this case, it's rather from a weld bead that a crack can start.
Nota...Finishing treatments can delay this phase, thereby considerably improving the structure's lifespan.
