Fatigue

Description

The structural weakening, and eventual failure, of a material due to repeated stress. Fatigue may start as a microscopic crack that spreads until the material is too weak to carry the load. Fatigue life and fatigue strength are measurements of the time and load that a material can handle in repeated tension-compression cycles.
