Abstract:
The study reported in this paper was prompted by the need to understand the conditions under which shot-peening is expected to give improved fatigue strength to manufactured
parts. During the past 20 years a large amount of experimental data has been published indicating the beneficial effects of shot peening on the fatigue strength of both
laboratory specimens and manufactured parts. It is easier to isolate the effects produced by shot peening laboratory specimens than it is to isolate the effects produced by
shot peening manufactured parts. Therefore, in this paper, the data from fatigue tests on shot peened laboratory specimens are studied to isolate the important effects of
the shot peened manufactured parts are then studied to determine which factors must be considered that were not present in laboratory specimens. finally, a design procedure
is presented for evaluating the influence of shot peening on fatigue strength.
