🧪 PMMA colloidal glass flow curves (Petekidis, Vlassopoulos & Pusey 2004, Fig. 5)

dataset id: petekidis2004_fig5

Steady-state flow curves of hard-sphere PMMA colloidal glasses digitized from Fig. 5 of Petekidis, Vlassopoulos & Pusey, J. Phys.: Condens. Matter 16, S3955-S3963 (2004). Five volume fractions from 0.586 to 0.63. The original figure has normalized axes, so the recorded scale factors were applied: shear rate x 0.158 s^-1, stress x 0.0825 Pa, giving yield stresses of order 1-100 Pa, consistent with hard-sphere colloidal glasses at these volume fractions. One out-of-order digitization point in the 0.596 curve was fixed by sorting.
