Ductility versus Brittleness in Self-Assembled Transient Networks
Résumé
We show that two types of complex fluids belonging to the same class of soft materials (transient networks), and having the same linear rheological properties (Maxwell fluids) exhibit two distinct fracture behaviors as solids do. We have designed a third experimental system that captures the distinct features of both former ones. We show that it could be a good candidate to investigate the brittle-ductile transition in complex fluids.
