Figure 2. a–d) The evolution of the second principal curvature with respect to the first principal curvature for meta-plates with different values of the Poisson’s ratio (a), as well as different values of the thickness, h (b), unit cell thickness, t w
Figure 3. The effects of the width (W 0   = 92  mm) of the meta-plates on their shape under compression for two extreme cases with the a,c,e,g,i) negative and b,d,f,h,j) positive values of the Poisson’s ratios
Figure 4. a,b) Change in the absolute value of the second principal curvature with respect to the thickness of the plate for the most positive (a) and most negative (b) values of the Poisson’s ratios, respectively corresponding to θ  = 120° (ν  = 0.87)
Figure 5. a) Complex curvatures can result from a combination of auxetic and non-auxetic unit cells
