| 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. |
