New paper on "fracture diodes".

The final (?) paper “Fracture diodes: Directional asymmetry of fracture toughness”, stemming from the collaborative project “Designing Microstructures for Engineering Toughness”, DMS-1535076 has been accepted in Physical Review Letters.

In this article, we used numerical simulation and experiments to study meta-materials with directionally asymmetric fracture properties initially devised in (Hossain, Hsueh, Bourdin, & Bhattacharya, 2014).

Update: the article is now available (Brodnik et al., 2021) and has been featured in Physics, the online magazine from the American Physical Society.
