Changes　of　total　cyclic　strain　energy　at　the　notch　for　copper　film　specimen　were　analyzed　before　and　after　laser　irradiation　treatment.　The　results　showed　that　laser　irradiation　can　increase　total　cyclic　strain　energy　and　the　effect　of　increase　is　more　evident　for　the　damaged　copper　specimen.　Based　on　the　damage-healing　mechanism,　an　enhancement　parameter　and　a　healing　parameter　were　defined　by　the　local　cyclic　strain　energy.　A　new　model　based　on　local　strain　energy　was　proposed　to　predict　residual　fatigue　life　for　the　damaged　copper　film　specimen　after　laser　irradiation.　The　predicted　results　by　the　proposed　model　agree　well　with　the　experimental　lives.
