Abstract:  
DEAR READER…as you are aware, shot peening improves the fatigue strength of metal parts such as gears or springs. Shot peening improves fatigue strength through compressed residual stress. Arc height, measured with Almen strips, is commonly used as a parameter for understanding the strength of the shot peening process. This method was developed in 1945 and it is widely used today. The arc height and the residual stress have a correlation, but with the arc height it is not possible to know the exact value of the remaining residual stress in each part.
