I NTRODUCTION ncreasing the fatigue life of parts and constructions remains an urgent task in aircraft industry. One of the ways to extend fatigue life is to create a near-surface layer in material with compressive residual stresses. Laser shock peening (LSP) is one of the most promising methods of residual stress creation. In order to achieve optimal distribution of residual stress, it is necessary to accurately select the parameters of the laser pulse impact. Treatment of various parts, among I
