Note: Dirlik’s method (1985) remains a widely accepted industrial standard, validated for many Gaussian random vibrations.
Vibration fatigue is a critical failure mechanism in engineering structures subjected to dynamic, random, or cyclic loading. Unlike traditional stress‑life (S‑N) approaches that assume constant amplitude loading, real‑world excitations—such as wind turbulence, road roughness, or engine vibrations—are stochastic in nature. provide an efficient frequency‑domain framework to predict fatigue life under such random vibrations, eliminating the need for lengthy time‑domain simulations.
