Endowing variational phase-field fracture models with custom strength criteria
Roberto Alessi, Matteo Brunetti, Roshan Udaram Patil +1
By now, several approaches have been proposed to endow phase-field fracture models with the ability to describe crack nucleation under multiaxial stress states. These include techn…

Exploring energy minimization to model strain localization as a strong discontinuity using Physics Informed Neural Networks
Omar León, VÃctor Rivera, Angel Vázquez-Patiño +2
We explore the possibilities of using energy minimization for the numerical modeling of strain localization in solids as a sharp discontinuity in the displacement field. For this p…
