Comparison between the improvements made to the fatigue strength of stainless steel by cavitation peening, water jet peening, shot peening and laser peening
TL;DR: In this article, a plate bending fatigue test was conducted to compare the performance of various peening methods used to improve the fatigue strength of stainless steel 316L, and the optimum coverage was examined by measuring the fatigue life at constant bending stress.
Fatigue crack propagation in the presence of shot-peening residual stresses
TL;DR: In this article, the effects of peening and re-peening on the fatigue fracture behavior of metallic components in the presence of shot peening residual stresses were examined. But, only the steel specimens showed further life enhancement.

Improvement of Fatigue Strength of Aluminum Alloy by Cavitation Shotless Peening
TL;DR: Cavitation shotless peening as discussed by the authors uses a submerged high speed water jet with cavitation to modify surfaces in the same way as shot peening, where no solid body collisions occur in this peening process.
