Direct Confocal Imaging of Fracture Precursors in Casein Gel

Explore a 28-minute conference talk on direct confocal imaging of fracture precursors in casein gel, presented by Mathieu Leocmach at the Erwin Schrödinger International Institute for Mathematics and Physics (ESI). Delve into the complex delayed yielding behavior of gels under sub-critical stress and the importance of understanding precursors before catastrophic failure. Learn about the ICAMM setup, designed for integration with confocal microscopes, allowing precise stress application and measurement. Discover how 3D implementation of dense optical flow algorithms on confocal images enables detection and statistical analysis of structural precursors, such as strand breaking events. Gain insights from this presentation, which was part of the Thematic Programme on "Non-equilibrium Processes in Physics and Biology" at ESI in 2024.
