Multiple Healing Fatigue Damage by Laser Shock Peening for Copper Thin Film

Abstract:

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.
