Consecutive shock waves and fatigue loads: action invariants as optimization parameters under Laser Shock Pinning

Mikhail Bannikov, Oleg Naimark, Aleksandr Balakhnin, Vladimir Oborin, Sergey Uvarov, Aleksandra Yurina

The criteria for optimizing shock-wave modes to increase the fatigue life of aircraft engine alloys are discussed with reference to laser shock peening (LSP). They are based on the self-similarity of plastic wave fronts and the kinetics of…
