Convergence of domain integrals for stress intensity factor extraction in 2-D curved cracks problems with the extended finite element method

González Albuixech, Vicente Francisco; Giner Maravilla, Eugenio; Tarancón Caro, José Enrique; Fuenmayor Fernández, Francisco Javier; Gravouil, A. (Wiley, 2013-05-25)

The aim of this study is the analysis of the convergence rates achieved with domain energy integrals for the computation of the stress intensity factors (SIF) when solving 2-D curved crack problems with the extended FEM ...
Domain integral formulation for 3-D curved and non-planar cracks with the extended finite element method

González Albuixech, Vicente Francisco; Giner Maravilla, Eugenio; Tarancón Caro, José Enrique; Fuenmayor Fernández, Francisco Javier; Gravouil, Anthony (Elsevier, 2013-05-30)

The computation of stress intensity factors (SIFS) in curved and non-planar cracks using domain integrals introduces some difficulties related to the use of curvilinear gradients. Several approaches exist in the literature ...
