The maximum stress below which a material can presumably endure an infinite number of stress cycles. If the stress is not completely reversed, the value of the mean stress, the minimum stress, or the stress ratio should be stated.
The maximum value of the applied alternating stress that the material can withstand without failure ever occurring.
A characteristic of the material and its geometry. If a material is loaded below the fatigue limit, the material will not fail, regardless of the number of cycles it is subject to.
Maximum fluctuating stress a material can endure for an infinite number of cycles. It is usually determined from an S-N diagram and is equal to the stress corresponding to the asymptote of the locus of points corresponding to the fatigue life of a number of fatigue test specimens. An alternate term is endurance limit
a value below which a material no longer exhibits cyclic stress failure
See "Endurance Limit."
The maximum stress that presumably leads to fatigue fracture in a specified number of stress cycles. If the stress is not completely reversed. the value of the mean stress. the minimum stress, or the stress ratio should also be stated. Compare with endurance limit.
The maximum value of the applied alternating stress which a test piece can stand indefinitely.
Maximum stress that a material will endure without failure for an infinite number of load cycles.
Fatigue limit, also known as stress limit, is a property of ferrous iron alloys and titanium http://www.royweb.ic24.net/Useful_Tables/Fatigue/Fatigue.html. 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.
