Dynamic brittle fracture using Lip-field approach in an explicit dynamics context
Rajasekar Gopalsamy, Nicolas Chevaugeon
This paper aims to investigate the dynamic response of a material body undergoing fracture subjected to high strain rate loading conditions such as impact or explosion. In particul…

Phase-field and lip-field approaches for fracture with extreme mesh deformation (X-Mesh): a one-dimensional study
Nicolas Moës, Benoît Lé, Nicolas Chevaugeon +1
We consider a one-dimensional fracture problem modelled using either the phase-field or lip-field approach. In both cases, we optimise the incremental potential with respect to the…

Lipschitz regularization for softening material models: the Lip-field approach
Nicolas Moes, Nicolas Chevaugeon
Softening material models are known to trigger spurious localizations.This may be shown theoretically by the existence of solutions with zero dissipation when localization occurs a…
