Stress-velocity relations. Network growth velocity vp as a function of the applied stress σnn in both the link-dominated uncoupled regime (A and B) and the elasticity-dominated coupled regime (C and D). Shadowed areas indicate pulling stresses. (A and B) The link-dominated uncoupled regime, showing the dependence of the stress-velocity relation on the ratio ka/kd0 (ka/kd0=10,1,0.1; continuous black line, dashed red line, and dashed-dotted blue line, respectively) for small and large loading rates, (A) k0/kd0=0.1 and (B) k0/kd0=102, respectively. The dots correspond to the critical pulling stress of each curve. (C and D) The elasticity-dominated coupled regime, showing the dependence of the stress-velocity relation on the parameter Eb/ρfkBT for (C) ka/kd0=1(Eb/ρfkBT=0.28,0.028,0.0028; continuous black line, dashed red line, and dashed-dotted blue line, respectively) and (D) ka/kd0=10(Eb/ρfkBT=1.15,0.115,0.0115; continuous black line, dashed red line, and dashed-dotted blue line, respectively). The values of the parameters for the stress-velocity relations shown are marked as dots in Fig. 4E. (In color online.)
