Gradient plasticity crack tip characterization by means of the extended finite element method (MATLAB code included)
I hope some of you may find this work interesting, the X-FEM non-linear code developed (incorporating linear elasticity, J2 plasticity, and Strain Gradient Plasticity) can be downloaded from www.empaneda.com/codes
