Une méthode hybride analytique et éléments finis étendus est utilisée pour étudier la propagation de fissures courbes en mode mixte. Un essai sur un spécimen doublement entaillé est simulé. Un traitement spécifique de l'amorçage de la fissure à partir d'une entaille large est proposé dans le cadre de cette méthode. La trajectoire de la fissure est en bon accord avec des résultats expérimentaux de la littérature.

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.
