Abstract:
INTRODUCTION
It is somewhat less than a quarter of a century since shot peening was first used consciously to improve the fatigue strength of metal parts. During this time, considerable
effort has been spent toward finding the improvement attainable in specific applications and methods for attaining this improvement. While all the factors which affect the
improvement are not completely understood, a number of useful ideas concerning the mechanism of improvement have been advanced. The objective of this paper is to review
these ideas toward an appreciation of the present status of understanding the effect of shot peening upon fatigue strength.
