This paper presents a study on the application of the weight function and finiteelement methods to evaluate residual stress intensity factors in welded testsamples. Three specimen geometries and various residual stress profiles werestudied. Comparisons of the two different methods were made in terms of theaccuracy, easiness to use, conditions and limitations. Calculated residualstress intensity factors by the two different methods are in general in goodagreement for all the configurations studied. Computational issues involved inexecuting these methods are discussed. Some practical issues are also addressed,e.g. treatment of incomplete or limited residual stress measurements, influenceof transverse residual stresses, and modelling residual stress in short-lengthspecimens. The finite element method is validated by well-established weightfunctions and thus can be applied to complex geometries following the proceduresrecommended in this paper. (C) 2010 Elsevier Ltd.
