Laser shock processing (LSP) is a newly developed surface treatment to
provide residual stress fields in metallic materials using laser-induced high
pressure surface plasmas.
First of all, it is shown in this paper that most of the
physical and mechanical aspects of LSP have been investigated recently for
different process configurations, resulting in a good global understanding of
the phenomena involved.
By having a short overview on many recent studies involving LSP, some
general features could be drawn about the ability of the process to harden and
strengthen metallic materials.
Particular attention was given to the residual
stress~fields induced on several industrial metals.
Lastly, fatigue applications on different Aluminum alloys and stee...
