By pressing GCr15 steel balls with different diameters statically into 40Cr steel targets with different hardness, the relationship among diameter of dent, load, diameter of ball and mechanicall property of target material was studied. From the test results a method to determine the equivalent load during shot peening was proposed. Using the equivalent load, we can calculate the residual stress field induced by shot peening according to an analytical model proposedsed by the authors. The calculated results were verified by experimental data quite well. Descriptors: Shot peening; Residual stress; Dent
