There, it is possible to see how the ratio of average fatigue life between shot peened specimens and untreated specimens for lives less than 105 cycles is around 4, and for lives greater than 105 cycles is 14. This suggests that the influence on life due to SP on the specimens is higher...
The compacted graphite iron was more affected by shot peening than the grey cast iron, meaning that the same shot peening parameters resulted in both higher compressive stresses and larger deformation depth.Mattias LundbergRu Lin PengSten JohanssonMaqsood AhmadTaina VuoristoDaniel Backstrom...
