Abstract: The residual stress field due to shot peening for 9 kinds of shot peening regime of 40Cr steel was calculated using the finite element program ADINA-84 of elastic-plastic analysis. The formula for caculating the tensile residual stress field was obtained. According to the fatigue test results, the concept of IFL due to shot peening were established.

Key words: shot peening, residual stress, fatigue strength
