Study of some optimal XFEM type methods [PDF]
, 2007 The XFEM method in fracture mechanics is revisited. A first improvement is considered using an enlarged fixed enrichment subdomain aroud the crack tip and a bonding condition for the corresponding degree of freedom.

Numerical aspects of the XFEM — The XFEM p–Version [PDF]
PAMM, 2006 AbstractThe XFEM is known to approximate the displacements and stresses around a crack tip in a very efficient way. But as we will present in this paper we have to deal with a phenomenon coming along with this method that compels us to use higher order shape functions for those elements that are enriched by the crack tip functions.For the computation ...
