Figure 6.

(A) Normalized initial shear modulus, $G_0/G_{0\text{a}}$, of the RCL network with $l_{\text{c}}=0.86\mu \text{m}$ versus characteristic ratio $l_{\text{b}}/l_{\text{c}}$, where $G_{0\text{a}}$ is the initial shear modulus calculated for the RCL F-actin network with $\mu ={\mu }_{\text{a}}=4\times {10}^{-8}$ N and $\kappa ={\kappa }_{\text{a}}=6.75\times {10}^{-26}$ N/m. The $l_{\text{b}}/l_{\text{c}}$ for the RCL F-actin network is indicated by the star. Larger values of $l_{\text{b}}/l_{\text{c}}$ are obtained either for $\mu <{\mu }_{\text{a}}$ and constant $\kappa ={\kappa }_{\text{a}}$ (magenta solid symbols) or for $\kappa >{\kappa }_{\text{a}}$ and constant $\mu ={\mu }_{\text{a}}$ (blue open symbols). The straight lines indicate the scaling laws of open-cell foams for the two extreme limits 1. (B and C) The large strain response of the RCL network for various $l_{\text{b}}/l_{\text{c}}$ ratios shown in (A), where $G/G_0$ is the network shear modulus scaled by the initial modulus, $G_0$, and $\text{T}/{\text{T}}_{\text{c}}$ is the stress scaled by the stress value at the onset of nonlinearity, ${\text{T}}_{\text{c}}$.
