The morphology of MAX phase composites is examined here. Specifically, crack branching is examined in Al - Ti2AlC composites showing the role of MAX phase distribution on the fracture performance of such materials. Ductile alloy phases serve to deflect cracks in the hard, yet tough, MAX phase.

The USACM is happy to announce a virtual seminar this week on Wednesday, July 1st at 3pm Eastern. The title of the seminar is "Examining Fracture Behavior in Heterogeneous Poro-Elastic Media from Nano to Macro-Scale". An abstract of the talk is available here:

We have a number of seats available to anyone interested. We just ask attendees to register at this page:
Twenty years in since their introduction, it is now plain that the regularized formulations dubbed as phase-field of the variational theory of brittle fracture of Francfort and Marigo (1998) provide a powerful macroscopic theory to describe and predict the propagation of cracks in linear elastic brittle materials under arbitrary quasistatic loading conditions. Over the past ten years, the ability of the phase-field approach to also possibly describe and predict crack nucleation has been under intense investigation.
Dear colleagues,
There is a new opening for one postdoc position, to be filled immediately, in my research group in the Department of Civil Engineering and Engineering Mechanics at Columbia University. We are looking for postdocs in the broad area of computational mechanics. Candidates should have expertise in modeling dynamic responses of path-dependent materials. Our project is specifically focused on applications of machine learning (reinforcement learning, graph embedding) for computational plasticity and damage.
Published in Extreme Mechanics Letters: https://doi.org/10.1016/j.eml.2020.100685. Catastrophic failure of materials and structures due to unstable crack growth could be prevented if fracture toughness could be enhanced at will through structural design, but how can this be possible if fracture toughness is a material constant related to energy dissipation in the vicinity of a propagating crack tip.
