Abstract:
ABSTRACT
Compressive surface stresses are found to enhance the fatigue life of components, as fatigue cracks originate mostly from surfaces. From among the various surface
enhancement processes, this review paper focuses on shot peening methods since they are the most complex in evaluating the material response due to the inherent stochastic
nature of several variables. Peening can produce different amounts of near surface plastic deformation for the same residual stress and vice versa for different combinations
of input parameters. Knowing the reasons why such variations occur will enhance the understanding of shot peening and other residual stress inducing processes. Many
researchers have
done experimental and theoretical studies to understand the underlying mechanisms of shot peening. This paper provides an overview of that extensive research and suggests
some remaining tasks.
