Vibration fatigue using modal decomposition (2018, unknown): “Cycle-amplitude distribution To identify the damage, an estimate of the cycle-amplitude distribution of the equivalent stress-response PSD Sc(ω) is needed; most frequency domain methods require spectral moments [22, 42], which are thus introduced for the reduced EVMS modal stress PSD.”
Fatigue predictions in entire body of metallic structures from a limited number of vibration sensors using Kalman filtering (2011, background): “In the literature, several spectral-based approximations [4–7,9–16] have been proposed to compute fatigue lifetime in terms of the spectral moments of the stress process.”
Uncertainty in fatigue life prediction of structures subject to Gaussian loads (2009, unknown): “Tovo [37] proposed to use dBT (k) = (p+ (1− p)α 2 )d2(k), (58) with p = min((α1 − α2)/(1 − α1), 1).”
Moment-Based Translation Model for Hardening Non-Gaussian Response Processes (2016, methodology): “From a comprehensive analysis for a variety of broad-band Gaussian processes with different spectral shapes, a linear combination rule to approximate the rainflow counting damage was proposed (Tovo 2002; Benasciutti and Tovo 2006):”
