Figure 4

(a) Distribution of local stiffnesses kloc for RGG network versus average coordination number of vertices, z, at force dipole length d=15 μm and ratio of the bending modulus to the stretching modulus . (b,c) Joint distribution of local stiffness and number of local fibres NF, defined as a weighted fraction of local bonds, with bond weight=1 below a short-range cutoff and decaying as 1/R2D beyond, where (b) for RGG network () and (c) for collagen network (). Dashed lines show the macroscopic shear moduli of the networks as a function of average number of local fibres .
