In this study, researchers from the Research Center UNIZA  drew on their many years of experience with the X-ray diffraction method and its use for evaluating residual stresses.<\/p>\n\n\n\n<p>The study was published in a renowned journal <strong>Engineering Fracture Mechanics<\/strong> (Q1, Impact Factor 5.3).
