A Hybrid Analytical and eXtended finite element method (HAX-FEM) is proposed to study the propagation of curved mixed-mode cracks. A Double Edge Notched test on a concrete sample is simulated. A specific treatment is proposed to account for crack initiation from a finite width notch. The crack morphology is in good agreement with previously published experimental results.
