Abstract
Based on quantitative comparisons of weigh functions (WFs) for various crack geometries, this chapter discusses the effect of overall as well as local geometry of the cracked body on the WF; assesses the rationality of the “substitute geometry” concept by using simple model crack geometry for more complicated crack geometries; provides the way of using the “substitute geometry” concept to analyze engineering crack problems associated with more complicated real world crack geometries. A brief discussion is made on another approach for analyzing cracks in complex geometries, namely the composition of SIF weight functions.
