The tri‐axial X‐ray stress analysis allows, together with boundary conditions and fitting curves, a control of measurements and calculations for the determination in‐situ of Poisson's ratio and stress free lattice spacing. A complete internal stress field analysis is discussed in terms of the ‘X‐ray integral method’ on rolled steel discs of 100 Cr‐6 (ASTM: A 295, BS: 970/2).
