Abstract:  
ESDU 92015 - Shot peening can produce significant increases in the fatigue strength of many components. This Item presents data from a large number of fatigue endurance tests carried out on steels, titanium alloy and aluminium alloys. These data show the increases in fatigue strength it is possible to achieve with shot peening. Data were obtained from fatigue and fretting fatigue tests. Data are provided for various specimen types including welded specimens. Most of the tests were carried out in air at room temprature but a few tests were carried out in salt water or at elevated temparatures. The data are presented in 17 figures, mostly as S-N curves. The fatigues are accompanied by tables which provide the test details.
