What is Fatigue Life – S

S-N curve, also known as a Whler curve plots applied stress (S) against component life or number of cycles to failure (N). Engineers use this method to determine the fatigue life of a material. In materials science, fatigue is the weakening of a material caused by cyclic loading that results in progressive, brittle and localized structural damage.
