The effects of deep rolling and shot peening on fretting fatigue resistance of Aluminum-7075-T6

The effect of shot peening (SP) and deep rolling (DR) on fretting fatigue life of Aliminum7075-T6 is investigated in this work. The results show that fretting fatigue reduces the normal fatigue life by 67%. For low cycle fatigue, SP while being superior to DR, increases the fretting fatigue life by 300% for the specimens tested in this work. For high cycle fatigue, however, the effect of DR on fretting fatigue resistance is more profound than SP such that an increase of about 700% is observed for DR. Numerical simulation of SP and DR is also performed in this work. The results indicate that DR gives rise to a larger compressive residual stress than SP under the conditions considered in the simulations. This agrees quantitatively with the experimental results obtained from high cycle fatigue tests.
