Robust preconditioning for a mixed formulation of phase-field fracture problems
Timo Heister, Katrin Mang, Thomas Wick
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 elasticity…

A mixed phase-field fracture model for crack propagation in punctured EPDM strips
Katrin Mang, Andreas Fehse, Nils Hendrik Kröger +1
In this work, we present crack propagation experiments evaluated by digital image correlation (DIC) for a carbon black filled ethylene propylene diene monomer rubber (EPDM) and num…

Mesh adaptivity for quasi-static phase-field fractures based on a residual-type a posteriori error estimator
Katrin Mang, Mirjam Walloth, Thomas Wick +1
In this work, we consider adaptive mesh refinement for a monolithic phase-field description for fractures in brittle materials. Our approach is based on an a posteriori error estim…
