| Abstract: | The work examines the effect of controlled shot peening (CSP), laser shock peening (LSP) and ultrasonic impact treatment (UIT) on the fatigue behavior of 2024-T351 aluminum alloy. The testing methodology has been designed to extract information regarding specific products of the treatments and their individual affect on fatigue damage. The work concludes that all three surface treatments improve the fatigue resistance of the material with the LSP covering the areas of safe-life and damage tolerance, the control shot peening can only benefit the area of short crack growth while the UIT proved to benefit both the short and long crack growth. |
