Document ID: VF-SM-2025-01 Version: 1.0 Target audience: Mechanical engineers, durability specialists, structural analysts 1. Introduction Vibration fatigue deals with the damage and lifetime estimation of structures subjected to dynamic, random, or harmonic excitations. Unlike traditional stress-life (S-N) or strain-life (ε-N) approaches applied to deterministic load histories, vibration fatigue often faces stochastic loads—e.g., wind, road roughness, or engine vibrations. vibration fatigue often faces stochastic loads—e.g.
