Verification of brittle fracture criteria for elements with V-shaped notches

In this paper an analysis of crack initiation in plane elements with V-shaped notches under biaxial loading (mode I and II) was presented. The following fracture criteria were used to evaluate the critical loads and directions of crack initiation: strain energy release rate criterion; strain energy density criterion; modified McClintockʹs stress criterion; non-local stress criterion. s of numerical analysis obtained using the boundary element method and path independent H and J integrals were compared with experimental data.
