🧪 Soft particle glass flow curves, supplementary set B (Seth et al. 2011, Fig. S4b)

dataset id: seth2011_S4b

Steady-state flow curves of jammed soft-particle glasses digitized from supplementary Fig. S4b of Seth et al., Nature Mater. 10, 838-843 (2011). Three volume fractions (0.72, 0.75, 0.86). Companion to the S4a set, covering a second batch of the same soft-particle system; the paper’s micromechanical model is compared against both sets. One small digitization glitch in the 0.72 curve (single out-of-order point) was fixed by sorting.
