Definition

The effect by which vibration—periodic, transient or random dynamic loading—produces stress cycles that initiate and propagate fatigue cracks in structural components; the interaction emphasizes the role of modal response, dynamic amplification, and spectral content in determining fatigue damage accumulation.
