A simplified continuous–discontinuous approach to fracture based on decoupled localizing gradient damage method

In this work, two fracture modelling methods i.e., extended FEM (XFEM) and localizing gradient damage method (LGDM), are combined to get the advantages of both methods while eliminating their limitations. The LGDM is a micromechanics-based method that avoids spurious damage growth and incorrect damage initiation observed in conventional gradient damage method (CGDM). However, in the LGDM, a cracked/discontinuous domain is not fully realized due...
