A robust mixed finite element formulation for third medium contact
M. Vorwerk, J. Schröder, P. Wriggers
Third medium contact provides a smooth continuum alternative to classical contact algorithms by replacing explicit contact constraints with a highly compliant fictitious medium. In…
Bayesian inversion for unified ductile phase-field fracture
Nima Noii, Amirreza Khodadadian, Jacinto Ulloa +4
The prediction of crack initiation and propagation in ductile failure processes are challenging tasks for the design and fabrication of metallic materials and structures on a large…
Multilevel Global-Local techniques for adaptive ductile phase-field fracture
Fadi Aldakheel, Nima Noii, Thomas Wick +2
This paper outlines a rigorous variational-based multilevel Global-Local formulation for ductile fracture. Here, a phase-field formulation is used to resolve failure mechanisms by…
The Neural Particle Method -- An Updated Lagrangian Physics Informed Neural Network for Computational Fluid Dynamics
Henning Wessels, Christian Weißenfels, Peter Wriggers
Numerical simulation is indispensable in industrial design processes. It can replace expensive experiments and even reduce the need for prototypes. While products designed with the…
Virtual Element Formulation For Finite Strain Elastodynamics
M. Cihan, F. Aldakheel, B. Hudobivnik +1
This work provides an efficient virtual element scheme for the modeling of nonlinear elastodynamics undergoing large deformations. The virtual element method (VEM) has been applied…
A global-local approach for hydraulic phase-field fracture in poroelastic media
Fadi Aldakheel, Nima Noii, Thomas Wick +1
In this work, phase-field modeling of hydraulic fractures in porous media is extended towards a global-local approach. Therein, the failure behavior is solely analyzed in a (small)…
