Secondly, the stress spectral moment is rapidly evaluated by summing the modal contributions. The procedure decouples the spatial and frequency information inherent in the spectral moment. Then, a fatigue damage response spectrum, independent of structural characteristics, is defined using the single-moment method. Finally, two new combination formulas are formulated to simplify the fatigue assessment into the weighted combination of modal damage responses.

Notably, the SP treatment applied to both the dovetail tenon and dovetail slot improved the fretting fatigue life by approximately 600% compared to the untreated specimens. This improvement is primarily attributed to the fact that the SP treatment introduced a certain depth of plastic deformation layer, and the presence of compressive residual stresses inhibited the crack initiation and early propagation rates.
