A study on the effect of residual stresses on hydride assisted crack in Zr-2.5Nb pressure tube material using XFEM

A simple and efficient implementation of localizing gradient damage method in COMSOL for fracture simulation

“…Computational fracture modeling is broadly categorized into discrete and smeared models (Ambati et al, 2014). In the discrete models, the crack is defined explicitly using either conformal mesh or nodal enrichment (Borst et al, 2004;Jha et al, 2022). In comparison, the smeared methods have diffused definitions of crack (i.e.…”
