Abstract:
The previous investigation about the influence of shot peening (SP) on the fatigue strength of aluminium alloy have pointed out that shot peening does not affect the fatigue
strength at lower stress near the fatigue limit, although it has pronounced influence on the fatigue strength at higher stress level in S-N curves. Besides, the influence
of the maximum value and the distribution of residual stress (RS) induced by SP on the fatigue behavior have been seldom investigated recently, although a lot of papers
about the relation between the fatigue strength and RS have been reported. Therefore the relationship between the fatigue behavior and SP effect as well as the optimum RS
field of high strength aluminium alloy have been investigated in the present article.
