Does this still apply to carbon fiber body planes like the 787? I know aluminum has can only be flexed so many times before it cracks but if the plane is made from a different material, would this rule still apply?
- gsnedders 9y agoYes. Every material ultimately has a fatigue limit; there's nothing you can stress indefinitely without it eventually breaking. Now, other materials can move the number of possible cycles up and down, and potentially move the number up sufficiently that it becomes a non-concern (because other factors would drive airlines to sell and scrap the old aircraft), but it'll never be infinite.
- ars 9y ago> Every material ultimately has a fatigue limit; there's nothing you can stress indefinitely without it eventually breaking. That's not entirely true, see: https://en.wikipedia.org/wiki/Fatigue_limit https://en.wikipedia.org/wiki/Fatigue_limit "Ferrous alloys and titanium alloys have a distinct limit, an amplitude below which there appears to be no number of cycles that will cause failure."
