摘要：

Multiple　healing　fatigue　damage　for　polycrystal　copper　film　was　investigated　by　laser　shock　peening　(LSP).　The　damaged　specimens　were　healed　several　times　under　the　optimal　laser　parameters.　The　relationship　among　the　fatigue　life,　healing　times　and　the　damage　degree　were　investigated.　The　experimental　results　showed　that　the　multiple　heal　based　on　LSP　can　maximize　fatigue　life　of　the　damaged　specimens　under　the　definite　optimal　condition　with　the　obtained　at　damage　degree　of　0.4　and　healing　times　of　3,　in　which　nearly　4.6　times　increase　in　residual　fatigue　life　for　the　damaged　specimens,　and　7.8　times　increase　in　the　accumulated　fatigue　life.　©　(2013)　Trans　Tech　Publications,　Switzerland.
