Abstract：

A　repair　method　for　fatigue　damage　was　studied　by　laser　shock　peening　(LSP)　with　excimer　laser　for　polycrystalline　copper　film.　Two　basic　effects　were　defined.　One　is　the　enhanced　effect,　which　improves　the　fatigue　life　for　the　non-damaged　specimen　by　LSP,　and　the　other　is　the　healing　effect,　which　has　a　further　improvement　for　the　damaged　specimens.　The　results　showed　that,　in　most　cases,　LSP　has　a　pure　healing　effect　in　addition　to　an　enhanced　effect　for　the　damaged　specimens.　The　energy　analysis　revealed　the　work　hardening　due　to　LSP　is　the　main　reason　for　the　improvement　of　residual　fatigue　lives　for　the　damaged　specimens.　(C)　2013　Elsevier　Ltd.　All　rights　reserved.
