A　healing　method　for　fatigue　damage　was　studied　by　laser　shock　peening　(LSP)　with　excimer　laser　for　polycrystalline　copper　film.　It　is　found　that　the　reduction　of　plastic　strain　range　due　to　laser　shock　peening　could　be　responsible　in　the　improvement　of　residual　fatigue　lives　for　the　damaged　specimens　by　LSP,　and　the　degree　of　reduction　in　plastic　strain　range　for　the　damaged　specimens　by　LSP　is　more　evident　when　the　stress　range　is　larger.　According　to　the　variation　of　the　fatigue　ductility　of　the　specimen　before　and　after　LSP,　a　unified　damage-healing　model　is　proposed　during　the　damage-healing　process　for　copper　specimens.　The　predicted　lives　by　the　proposed　method　agree　well　with　the　experimental　results.　(C)　2014　Elsevier　Ltd.　All　rights　reserved.
