N2 - <p>Our project aims to explore the design space of lattice metamaterials. Lattice metamaterials attract considerable interest for their exceptional performance and prospects for engineering applications. These databases are generated by a generic method under potential publication. These databases comprise over 1.8 million distinctive entries, especially including numerous unprecedented metamaterials. These databases will strongly advance the emerging data-driven design strategies. </p><p> </p><p><strong>Dataset S1 (.csv format).</strong> Entire feature database of the designed metamaterials, including coordinates of flattened node-sets and elements of flattened connectivity matrices within building blocks.</p><p><strong>SubDataset for architectural features ("group name"-features.csv).</strong> Eleven separated databases correspond to eleven metamaterial groups for convenient access.</p><p> </p><p><strong>Dataset S2 (.csv format).</strong> Entire mechanical property database including Young’s moduli, Poisson’s ratios, shear modulus and isotropy index.</p><p><strong>SubDataset for mechanical property ("group name"-mechanical property.csv).</strong> Eleven separated databases correspond to eleven metamaterial groups for convenient access.</p><p> </p><p><strong>The dataset is intended for reviews of potential publications and should not be cited or used before public publication.</strong></p> ER -
