Comparison of Spectral Fatigues Methodologies Using Equivalent Stresses Obtained by Mises and Battelle Applied to a Semi-submersible Platform

Dirlik and Tovo-Benasciutti Spectral Methods in Vibration Fatigue: A Review with a Historical Perspective

“…An example of frequency domain fatigue analysis of a semi-submersible platform is described in [53]. The study applies spectral methods with multiaxial fatigue criteria to the output of a three-dimensional finite element model.…”

Fracture, Fatigue, and Structural Integrity of Metallic Materials and Components Undergoing Random or Variable Amplitude Loadings

“…It was also suggested that, in the absence of a statistically significant number of small crack tests, the crack depth curve computed using ∆K thr = 0.3 MPa √ m may be a reasonable first estimate for the worst-case crack depth history. In this context, it should be noted that the USAF Durability Design Handbook [52] explains that the growth of small "lead" cracks, i.e., the fastest growing cracks in an airframe or a component [53,54], in military aircraft is generally exponential. Indeed, this exponential crack growth model is contained within the USAF approach to assessing the risk of failure [55].…”
