Modeling strong/weak discontinuities by local mesh refinement variable-node XFEM with object-oriented implementation

•Numerical simulation for strong and weak discontinuities by local mesh refinement variable-node XFEM is presented.•A novel local mesh refinement scheme is proposed to model crack growth.•A Matlab object-oriented framework for the variable-node XFEM is developed.•Numerical examples demonstrate the s...
