Nondestructive identification of multiple flaws using XFEM and a topologically adapting artificial bee colony algorithm

SUMMARYWe present a novel algorithm based on the extended finite element method (XFEM) and an enhanced artificial bee colony (EABC) algorithm to detect and quantify multiple flaws in structures. The concept is based on recent work that have shown the excellent synergy between XFEM, used to model the...
