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…
Variational Approach to Viscoelastic Fracture : Comparison of a phase-field and of a lip-field approach
Rajasekar Gopalsamy, Nicolas Chevaugeon, Olivier Chupin +1
Fracture of viscoelastic materials is considered to be a complex phenomenon due to their highly rate sensitive behavior. In this context, we are interested in the quasi-static resp…
Lipschitz regularization for fracture: the Lip-field approach
N. Chevaugeon, N. Moes
The Lip-field approach is a new regularization method for softening material material models. It was presented first in a previous paper providing one-dimensional simulations for d…
The eXtreme Mesh deformation approach (X-MESH) for the Stefan phase-change model
Nicolas Moes, Jean-Francois Remacle, Jonathan Lambrechts +2
The eXtreme Mesh deformation approach (X-MESH) is a new paradigm to follow sharp interfaces without remeshing and without changing the mesh topology. Even though the mesh does not…
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…
