A phase-field numerical framework to study ductile damage to fracture transition: An application to material forming processes
Résumé
Abstract. In this work we present a phase-field based method to accurately predict the nucleation and evolution of damage. The damage pattern is then used as a criterion for automatic, remeshing-based, 3D crack insertion and propagation. The proposed framework has been implemented in Forge® finite element software and it offers a robust numerical tool for the modeling of damage to fracture transition in complex industrial processes. A bar shearing simulation will be used to show the robustness and efficiency of the approach. The flexibility of the approach is presented through the use of different damage criteria introduced into the phase-field formulation.
