Figure 5.

Effect of A/L, w/L, t/L, and n on the macroscopic Poisson’s ratio of the 3D planar metamaterials, ν _yx. Evolution of ν _yx as a function of A/L is shown in (a) for five different values of w/L (assuming t/L = 0.1), in (b) for five different values of t/L (assuming w/L = 0.1). Evolution of ν _yx as a function of nominal strain is shown in (c) for five different values of A/L (assuming t/L = 0.1 and w/L = 0.1), and in (d) for three different values of n (assuming A/L = 0.2, t/L = 0.1 and w/L = 0.1).
