An effective computational approach based on XFEM and a novel three-step detection algorithm for multiple complex flaw clusters

•An effective computational approach for detecting multiple complex flaw clusters is presented.•Forward problem is solved by XFEM to avoid re-meshing as changing the flaw geometry.•A novel three-step strategy is developed for solving inverse problem.•“Queue and Kill” method is proposed to identify a...
