| Outline of Final Research Achievements |
Not only the evaluation of the fatigue strength for shot-peened material but also the development of the technique for controlling the surface properties of material by shot-peening process play an important part in controlling the fatigue fracture of structures by shot-peening process. In the present study, the response surface model which can represent the quantitative relationship between the shot-peening conditions and the surface properties of material has been developed by introducing the design of experiments. It was indicated that the surface properties of fatigue specimens predicted by the response surface model agreed roughly with the experiments.
