Abstract:
A simple theoretical analysis of the shot peening process is presented. The process is viewed as one involving multiple and progressively repeated impact. The residual
stress field under each impact interacts with similarly produced neighbouring fields to finally produce a residual stress distribution varying in depth but uniform in
planes, parallel to the surface. Non-dimensional numbers which are useful for similarity considerations are introduced. New concepts such as shakedown, reversed plastic
yielding and Bauschinger effect as well as strain rate are thought to contribute a significant role in the process.
