Von Mises stress at each step of a non-intrusive Abaqus-ISET analysis of a surface crack—a initial global von Mises—b local von Mises—c enriched global von Mises. a Presents the simple stress field without fracture. b Introduces the stress singularity from the surface crack. c Presents (GFEM\(^\text {gl}\)) transfer of the singular stress state back to the enriched global problem
