X-ray stress measurement is a very useful method to evaluate the residual stress in polycrystalline materials. In the practical measurements, many conditions, such as the diffraction plane and scanning method of the detector, must be determined. These conditions are totally dependent on the purpose of measurements, and it requires much technical knowledge to set the conditions properly. Thus, an expert system for X-ray stress measurement was developed in the present paper, which can be utilized to determine the measuring conditions. The residual stress of the low carbon steel was measured employing the conditions suggested by the system. The experimental results were quite satisfactory, and the residual stress was evaluated reasonably. It can be said that the present system will help users to determine the measuring conditions for the various purposes of studies.
