2009:15 Improvement and Validation of Weld Residual Stress Modelling Procedure
Weld residual stresses have a large influence on the behavior of cracks growing under normal operation loads and on the leakage-flow from a through-wall crack. Accurate prediction of these events is important ... research results in the field of WRS. The major changes applied in the new weld residual stress modelling procedure are: Improved procedure for heat source calibration based on use of analytical solutions...
