Deep dives and metal stress?
Posted by: Leif... ()

I often hear about u-boats going very deep, far beyond test depth. But how often was this really done?

For instance if a type VIIc goes down to 240m and then up again without any problem, how dangerous would it be for that boat to go down to this depth again?
Would it be safe to do so since the boat has done it before, or would it be dangerous to even come close to this depth again due to metal fatigue?

Is the test depth the depth that the boat can dive to numerous numbers of times without causing permanent stress damage to the hull? Or would even a dive to test depth move the crush depth up a significant bit?
