In order to improve product performance and assess product life, it is necessary to measure and analyse the XRD patterns of the entire surface of materials constituting the product using high intensity and high brightness synchrotron radiation to determine the residual stresses of the materials. However, (i) the throughput of XRD pattern analysis has not improved much, and (ii) manual analysis of a large number of XRD patterns causes artificial dispersion and bias in the results. Therefore, in this study, an automated XRD pattern analysis method was developed and the residual stress distribution of resin materials was visualised.
