Abstract
We report an elastic instability associated with flow-induced clustering in non-Brownian colloidal nanotubes. Rheo-optical measurements are compared with recent simulations of mechanical flocculation in sheared fiber suspensions, and we observe an anomalous first normal stress difference that correlates with a contraction of diffuse vorticity-aligned domains. The nature of the response suggests that instabilities of this type are ubiquitous in complex fluids.Citation
