Crack-path selection in phase-field models for brittle fracture
W. Beck Andrews, Lars Pastewka
This work presents a critical overview of the effects of different aspects of model formulation on crack path selection in quasi-static phase field fracture. We consider different…

Effect of Transport Mechanism on the Coarsening of Bicontinuous Structures: A Comparison between Bulk and Surface Diffusion
W. Beck Andrews, Kate L. M. Elder, Peter W. Voorhees +1
Coarsening of bicontinuous microstructures is observed in a variety of systems, such as nanoporous metals and mixtures that have undergone spinodal decomposition. To better underst…
