FIGURE 4.

Mechanical properties of the cable network. (a) Effective Poisson ratio σ and (b) effective two-dimensional Young modulus E_2D for the triangular network as a function of the number of nodes in the test region. In both cases, red and blue curves are for networks without and with prestrain, respectively. (c) Forces at adhesion sites as a function of the resting length l_r, which determines the level of prestress in the network. Different curves correspond to different number of adhesions along a circular contour (8,12, 16, 20, 25, 35, 45, and 60 from top to bottom).
