The influence of machining on fatigue life

The residual compressive stress introduced by shot blasting/shot peening is a percentage of the final tensile stress strength, and this ratio increases as the strength/hardness of the part material itself increases. High-strength/hardness metals are more brittle and more sensitive to surface defects. Shot blasting/shot peening will allow these high-strength metals to be used in fatigue-prone working conditions. Aircraft landing gear is usually designed with a fatigue strength of 300 ksi (2068 MPa), combined with shot blasting/shot peening.
