Frequency Domain Analysis for Fatigue and Random Response

Frequency domain methods for fatigue analysis and for general random response analysis have experienced a resurgence over the last few years due to improved technology and better computational processes. Today, a complete range of models can be processed from full vehicle systems to local component systems. Single input loads and multiple correlated input loads can be processed. Complex loading conditions can be handled, which contain random and deterministic components like a sine sweep. Different kinds of fatigue life calculations can be done including both Stress-Life and Strain-Life approaches.
