Fracture Visualization

How do hydraulic fractures interact with pre-existing ones?

Serially reconstructed, high-resolution 3D fracture network of a hydraulically fractured sample under true triaxial stress conditions.

Book Structure Imaging

How were ancient books constructed and of what materials?

In collaboration with the Old Books New Science (OBNS) Lab at the University of Toronto, several micro-CT scans were undertaken to visualize the internal spine structure of a 17th century book (MSS 01106) from the Thomas Fisher Rare Book Library. The relatively denser ink can be seen as white spots, and the sewing structure of the spine can be seen going through the pages.

Bone Fracture Simulation

Can we use real geometry and FDEM to simulate how and when bones break?

A micro-CT scanned mouse femur was digitally reconstructed to create a 3D mesh and simulated using FDEM.
