SIFs evaluation of sharp V-notched fracture by XFEM and strain energy approach

Numerical estimation of stress intensity factors (SIFs), an important fracture mechanics parameter, for sharp V-notched structures is presented by using a new effective approach based on strain energy method associated with extended finite element method (XFEM). This approach takes advantages of both enrichments and the strain energy method. While enrichments allow the representation of notch-faces independent of the mesh, the strain energy...
