Analysis of the Effects of Aggressive Shot Peening on Fatigue Life of 7075 T6 Aluminum Alloy

For many years controlled shot peening was considered as a surface treatment. It is now clear that the performance of control shot peening in terms of fatigue depends on the balance between its beneficial (compressive residual stress and work hardening) and beneficial effects (surface hardening).The...
