Low cycle fatigue life and crack growth rates were analysis established for random load sequences, generated from three combat aircraft load exceedance curves using different algorithms, including simulated rain-flow cycle count,extreme-to-extreme excursions, upper to lower bound excursions and unrestricted peak-trough excursions. Also, the response of a fatigue meter to a random load sequence was simulated. Fatigue damage for the different load histories was computed using material constants for an Al-Cu alloy. Computed fatigue damage was relatively insensitive to the algorithm used for load sequence generation from combat aircraft load exceedance curves. Fatigue meter data based damage estimates were, however,sometimes unconservative.
