Improved conditioning and accuracy of a two-scale generalized finite element method for fracture mechanics
… of the GFEM/XFEM rely on the use of preselected enrichment functions that are known to ap- proximate the solution of a problem well. However, closed-form analytical enrichment functions are not always available. This research work focuses on advances of a two-scale GFEM for the accurate and …

A comparative study of stress intensity factor extraction techniques for the generalized finite element method
Generalized Finite Element Method (GFEM) is a Partition of Unity Method where shape functions are constructed by the product of standard finite element shape function and some additional shape functions. These additional shape functions take the benefit of some prior knowledge of the solution. They …
