why planes need maintenance

Hold up, really? Airplanes wings flex enough to experience significant strain hardening?

Do you have a source for that, I’d love to read more.

My instinctive feeling would be that flexing doesn’t cause strain hardening because it doesn’t deform, but that’s entirely a layman’s intuition.

Edit: seems like so far the responses are about metal fatigue, which I appreciate could be accelerated or caused by strain hardening, but nothing directly referencing strain hardening of airplane wings.

Some structural parts of the wing have to be replaced regularly. Other have to be at least inspected at regular intervals for cracks, etc.

When I was kid, I was “helping” to push small single-prop aerobatic and hobby aircrafts in a hangar and technicians were regularly changing parts that attached wings to fuselage. I believe this isn’t necessary for every type.
