Fatigue (material)Wikipedia
Materials fatigue performance is commonly characterized by an S-N curve also known as a Wöhler curve.This is often plotted with the cyclic stress (S) against the cycles to failure (N) on a logarithmic scale.S-N curves are derived from tests on samples of the material to be characterized (often called coupons or specimens) where a regular sinusoidal stress is applied by a testing machine
