Understanding Fatigue Failure: Causes, Risks & Prevention

The failure of a material due to repeated stressing is called fatigue failure. Fatigue failure occurs when a material is subjected to repeated cyclic loading and unloading, which can cause the material to fail at a stress level significantly lower than the material's yield strength. Fatigue failure is a common problem in engineering structures and components that are subjected to cyclic loading, such as aircraft wings, bridges, and car springs.
