Modèle à champ de phase pour la prédiction de la rupture des matériaux ductiles soumis à de grandes vitesses de déformation : développement numérique et validation expérimentale
Résumé
The study of crack initiation and propagation in ductile materials is crucial across various fields such as materials engineering, manufacturing, and structural design. Numerically predicting crack propagation with accuracy is paramount for evaluating the durability and reliability of components and structures. Among the methods used for this prediction are the Extended Finite Element Method (XFEM) and the Phase Field Method (PFM), the latter being the technique employed in this work. In this context, we will investigate crack propagation in ductile materials subjected to different deformation rates by implementing the Phase Field Method in the commercial finite element software Abaqus, using the explicit dynamic regime with the utilization of VUEL (Velocity User Element) and VUMAT (Velocity User Material) subroutines.
