The following is a quotation from a previous article in this series: “Science is almost always able to provide answers to questions about observed phenomena.
Introduction Shot peening is normally applied in order to improve the fatigue properties of components. This improvement is due to two factors:(1) Work-hardening of the
Shot peening induces a surface layer that contains compressive residual stress. It is this compressed surface layer that is largely responsible for improved fatigue performance
