# 🧪 Soft particle glass flow curves, supplementary set A (Seth et al. 2011, Fig. S4a)

`dataset id: seth2011_S4a`

Steady-state flow curves of jammed soft-particle glasses digitized from supplementary Fig. S4a of Seth et al., Nature Mater. 10, 838-843 (2011). Six volume fractions from 0.70 to 0.92. The paper introduces a micromechanical model predicting the flow of soft particle glasses from particle-scale contact mechanics; the supplementary flow curves support the model over a wide range of packing fractions. One duplicated trailing artifact point in the 0.92 curve was dropped during curation.
