| Method | Damage per sec | Lifetime (hours) | |---------------|----------------|------------------| | Time-domain RF| (3.2 \times 10^-8) | 8680 | | Narrowband | (7.1 \times 10^-8) | 3910 (underest.)| | Dirlik | (3.5 \times 10^-8) | 7930 (error 8.6%)|

(\lambda_0, \lambda_1, \lambda_2, \lambda_4) via numerical integration over frequency range. vibration fatigue by spectral methods pdf

[ E[\sigma^2] = \int_0^\infty G_\sigma\sigma(f) , df ] | Method | Damage per sec | Lifetime

[ \lambda_n = \int_0^\infty f^n , G_\sigma\sigma(f) , df, \quad n = 0,1,2,4 ] \quad n = 0

where (\Gamma) is the gamma function. This is for broadband signals. 4. Broadband Spectral Fatigue Criteria To address broadband processes, several frequency-domain methods have been developed: 4.1 Wirsching–Light (WL) Method Applies a correction factor (\rho(b,\gamma)) to the narrowband damage:
