# 🧪 Concentrated colloidal suspension flow curves (Pamvouxoglou et al. 2021, Fig. 6)

`dataset id: pamvouxoglou2021_fig6`

Steady-state flow curves of concentrated hard-sphere colloidal suspensions digitized from Fig. 6 of Pamvouxoglou, Schofield, Petekidis & Egelhaaf, J. Rheol. 65, 1219-1233 (2021). Three volume fractions (0.575, 0.602, 0.624) near the colloidal glass transition. The paper compares stress- versus strain-controlled shear and the yielding/relaxation behavior of the same suspensions; the digitized curves are the steady-state flow curves.
