Anisotropy tailoring in geometrically isotropic multi-material lattices

This article proposes the concept of anisotropy tailoring in multi-material lattices based on a mechanics-based bottom-up framework. It is widely known that isotropy in a mono-material lattice can be obtained when the microstructure has an isotropic geometry. For example, regular hexagonal lattices with a unit cell comprised of six equal members and equal internal angle of 120o each, show isotropy in the elastic properties. Such limited...
