Fatigue limit
From Wikipedia, the free encyclopedia
Fatigue limit, also known as stress limit, is a property of ferrous iron alloys and titanium [1]. It is the level of fatigue (cyclical stress) that can be repeatedly applied to and removed from a metal without ever causing it to fail no matter how many times the stress is cycled. Most metals, including structural materials such as aluminium, do not have a fatigue limit and will eventually fail even under very light loads if the load is cycled enough times.
