On the other hand, aluminum alloys do not have an endurance limit; if enough cycles are applied at even very low loads, they will eventually fail in fatigue. Fig. 1...

Thus, one of the main concerns is that the structure could sustain a low-velocity impact that no one is aware of that could then grow under either static or fatigue loading, eventually leading to failure. This concern has led to the concept of barely visible impact damage (BVID). BVID is a...

Once initiated, the fatigue fracture can propagate by high stresses and low cycles or by low stresses and high cycles. The final rupture may have characteristics of brittle and/or ductile fracture modes...
