Endurance Limit

 

the highest value of the stress amplitudes in a symmetrical cycle of mechanical load variation, or the maximum stress of an asymmetrical cycle, to which a material can be subjected for an unlimited number of cycles without failure. The value of the amplitude or the maximum stress in a cycle that, when repeated for a specific number of cycles, causes fatigue failure or produces macroscopic cracks is called the fatigue strength.
