Abstract

Bio-Inspired Metastructure Evolution In article number 2300019, Qianyun Zhang, Amir H. Alavi, and co-workers explore the principles of natural evolution for design and discovery of thousands of metastructures with hitherto unknown structures and new modalities of operation. The evolutionary computational approach uses representative unit cells with simple shapes to launch the evolutionary process and morphologically evolves complicated microstructures over generations. The framework is used to explore a series of 2D and 3D mechanical metamaterial structures with maximum bulk modulus, maximum shear modulus and minimum Poisson’s ratio.
