Abstract
Laser-shock surface treatment can create plastic strains and induce compressive residual stresses in metals. This process consists in irradiating a metallic sample with a short but intense laser pulse. As a consequence, a high temperature and pressure plasma is created at the sample surface. An elastic-plastic wave is then propagating in the sample creating plastic strains. This paper presents the effects of laser-induced stress waves on the residual stresses of a standard steel: the surface residual stress induced is approximately 0.6 times the compressive yield strengh of the material for a plastically affected depth of one millimeter.
