Figure 2.

Dependence of creep response on n. (A) $\epsilon$ versus time for σ = 10 Pa and n = 0.01 (red solid line), 0.03 (green dashed line), 0.1 (blue dashed line), 0.3 (cyan dash-dotted line), and 1 (magenta thin solid line). (B) Relative magnitudes of σ_e (open symbols) and σ_v (solid symbols) as a function of n for σ = 10 Pa. (C) η_eff versus n with σ = 10 Pa for n = 0.001 to 1. A dashed line indicates η_eff ∼ n⁻¹ for reference. In B and C, colored symbols correspond to the colored traces in A. (D) $\dot{\epsilon }$ as a function of σ for n = 0.03 (green circles), 0.1 (blue triangles), 0.3 (cyan diamonds), and 1 (magenta stars). For n≤ 0.3, the data are fit well by a single master equation (see Eq. 6). Dashed lines represent either ∼σ¹ or ∼σ⁰. To see this figure in color, go online.
