Analysis and Discussions on Weight Function Methods Based on Multiple Reference Load Cases,acements. The two methods are: the direct adjustment method (DAM) of Fett and Munz, and the universal weigh function method (UWFM) of Glinka and Shen, with different series forms for the WF-expressions. Detailed discussions are made on the commonalities and differences between the two approaches. Va

The best way to reveal the intrinsic accuracy of WFs is to employ Green’s functions (GF) for point-by-point comparison, instead of the customarily adopted comparisons of SIFs for some load cases.
