A microstructural defect-orientation informed phase field model
Micro-cracks, micro-voids and other such defects, which typically coalesce to form
macroscopic cracks, could be represented through incompatible, local rotations of material …

Phase-field fracture modeling, numerical solution, and simulations for compressible and incompressible solids
K Mang - 2022 - repo.uni-hannover.de
In this thesis, we develop phase-field fracture models for simulating fractures in
compressible and incompressible solids. Classical (primal) phase-field fracture models fail …

Robust preconditioning for a mixed formulation of phase-field fracture problems
In this work, we consider fracture propagation in nearly incompressible and (fully)
incompressible materials using a phase-field formulation. We use a mixed form of the …

Space-time modeling, analysis, and finite element simulations of phase-field fracture optimal control problems
D Khimin - 2024 - repo.uni-hannover.de
In this dissertation, we introduce for the first time, space-time formulations for phase-field
fracture optimal control problems. We develop the necessary theoretical framework, which …
