The K-T method is a spectral method that uses a kurtosis-based approach to estimate the fatigue damage rate.
Instead of analyzing a long, complex time signal, spectral methods use . A PSD provides a "map" of where energy is concentrated across different frequencies, allowing engineers to calculate fatigue life directly from the statistical properties of the load.

Fatigue is a critical failure mode in mechanical structures and components subjected to cyclic loading. Traditional fatigue analysis methods rely on the assumption of a deterministic loading history, which is often not the case in real-world applications. Many mechanical systems are subjected to random excitations, such as wind, road roughness, or ocean waves, which can lead to fatigue failure. Vibration fatigue analysis aims to predict the fatigue life of structures under such random loading conditions. The K-T method is a spectral method that
