From: Mining extreme properties from a large metamaterial database
A Effective Young’s Moduli, Ex = Ey, versus a variety of isomers, p4_1331_6Eq_7Strut_1204 ~ 1230. Subtle variations significantly enhance Young’s Modulus beyond four orders of magnitude. B Variation of Young’s modulus along the x direction, Ex versus a series of isomers, pmg_1242_6Eq_5Strut_18893 ~ 18919. Enhancement beyond three orders of magnitude for the modulus is beneficial to discover the unexplored extreme modulus. C Effect of isomers, cm_0001_4Eq_5Strut_1288 ~ 1314, on Poisson’s ratio along the y direction, νyx. With the same boundary node locations, various arrangements of the inside node and strut connectivity program extreme Poisson’s ratios across from negative to positive. D Examples of mining a metamaterial with extreme bi-mode by isomers, p4g_2213_6Eq_4Strut_7065 ~ 7092. The extensive architecture space in the large metamaterial database contributes to efficiently mining the rare isotropic bi-mode. Source data are provided as a Source Data file.
