I wonder how many cycles it had actually been through... When I think of cyclic fatigue, it is usually associated with numbers in the thousands, millions etc.... not a half dozen or so. Does anyone know how many trips the sub had taken to the depth of the Titanic either in use or testing? Was an identical shell tested in the lab to repeated pressure cycling that matched (or hopefully exceeded) the pressure levels that it would experience at the Titanic? I would hope so...
I’m quite familiar with the mechanism of metal fatigue but for my own interest, I’m going to have to study up more on what fatigue even means for a ‘carbon fiber’ construction.
