Comparison of KI calculation methods

Qian, Guian; González Albuixech, Vicente Francisco; Niffenegger, M.; Giner Maravilla, Eugenio (Elsevier, 2016-05)

This paper compares different numerical methods for mode I stress intensity factor (SIF) calculations. Both 2D and 3D models are used to calculate KI for the compact tension specimens. J-integral and interaction integral ...
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 ...
