What is a Fatigue Strength? - Definition from Corrosionpedia

Nov 22, 2013Fatigue strength is used to describe the amplitude (or range) of cyclic stress that can be applied to the material without causing fatigue failure, or the highest stress that a material can withstand for a given number of cycles without breaking. The standard fatigue strength for copper alloys is that reported for 100,000,000 cycles.
