Abstract: The contour method is a newly-invented destructive technique of residual stress measurement and has been receiving increasing interest. It is advisable to validate such new methods by comparison with other well-established techniques. For this purpose, contour measurements were performed on a MIG 2024-T351 aluminium alloy welded plate. The result has been compared with the results from neutron and synchrotron X-ray and shows a favourable agreement.
