Every cycled aluminum structure will (given enough cycles) fail this way. Aluminum has no 'endurance limit'. Steels, however, do. Steels can be designed to last an infinite number of loading/flexing cycles, whereas aluminum cannot.

This was one of the biggest criticism's on the Audi A8 "Spaceframe"
Because of the nature of Aluminum it would have a definite "service life" based on the duty cycles.
At some point - it would need to be scrapped and recycled.
