Brian Phung recently implemented a flexible numerical framework to simulate arbitrary 3D crack growth in heterogeneous materials. The framework involves adaptive remeshing on a voxel-based geometrical domain. Due to its modularity, the crack representation is de-coupled from the crack-evolution rule and material constitutive model (in the uncracked region), providing significant flexibility to investigate new or existing crack-growth criteria. The work has been published in the March 2019 issue of Engineering Fracture Mechanics. To download the article, click here or contact the MMM Lab.
