Rapid Fracture of Porous Materials

Many naturally occurring materials, e.g. wood and trabecular bone, have intricate porous microstructures and high density to toughness ratios. Due to their microstructure, these materials do not obey traditional continuum-based principles of fracture mechanics. In this project, the aim is to understand and predict rapid fractures in porous materials. Dynamic phase field finite element models are used to predict fracture numerically. The numerical experiments are complemented by mechanical testing and imaging (e.g. synchrotron radiation μCT) to improve the understanding of the fracture processes.
