Decomposed amplitude sweeps for the samples and model used in this study: (A) Carbopol, (B) Saramito model (Bingham version), (C) xanthan gum, (D) concentrated Ludox, (E) filled polymer, and (F) worm-like micelles. Green lines denote the slopes that lead to the dimensionless viscoplastic fragility number, as well the specific values for each material. The Saramito model parameters used here are ${\sigma }_y=94\hspace{0.17em}\text{Pa}$, $G=460\hspace{0.17em}\text{Pa}$, ${\eta }_s=20\hspace{0.17em}\text{Pa}\cdot \text{s}$, and ${\eta }_b=28\hspace{0.17em}\text{Pa}\cdot \text{s}$. (Model details can be found in SI Appendix.)
