Effect of Spectrum Editing on Fatigue Crack Initiation and Propagation in a Notched Member

Source

A method for eliminating small, nondamaging cycles from irregular loading histories is described. Analytic estimates of crack initiation, crack propagation, and total fatigue lives are compared to experimental data for full and edited load histories from the Society of Automotive Engineers Cumulative Fatigue Damage Test Program. Load histories edited to have equal crack initiation lives do not have equal crack propagation lives.
