.... Fatigue life was normally increased of four to five times, although improvements up to an order of magnitude were detected. Hardness measurements, profilometry, scanning electron microscopy, and X-ray diffractometry allowed interpreting the improvement of the fatigue behavior of the peened substrates...

... compared with X-ray diffraction measurements. Fatigue tests were done to compare the fatigue life of the holes with various chamfer sizes and angles. The cold expansion chamfered holes showed a clear improvement in fatigue life over cold expanded holes without chamfers. The sample material used...

.... Next, the fatigue life of smooth specimens is compared, both with and without dimples. It is indicated that the dimple has a benefit only to the repair case after the crack is initiated. Finally, stress intensity factors of a crack due to a dimple are numerically evaluated, and a guiding principle...
