- The paper provides detailed geometry, welding, materials properties data and residual stress measurements for validating complex weld simulation procedures. The significance of the work comes from its provision of validation benchmarks for finite element prediction of weld residual stresses in geometries at engineering-scale. This is important because previous benchmarks were derived at small-scale; the data here are more relevant for use in weld structural performance assessments of safety-critical plant components. The assessment covers both start-of-life residual stresses and the prediction of creep relaxation during high-temperature service. Development of this benchmark was funded by the EU, EPSRC and EDF Energy.
