Abstract Hierarchically designed metamaterials can be found in numerous fields such as hard biomaterials and man-made structures. Recently, additively manufactured metamaterials are very promising in meeting the increasing demands for materials providing nearly isotropic yield strength in lightweight engineering as the controlled micro-structures. In this paper, a novel hierarchically shell-plate lattice structures are introduced by placing the plates along the closed shell-based structures. With fixed relative density of 10% for hierarchical metamaterials, the effects of different cell sizes and shell thicknesses of shell lattice structures on isotropy are studied. Based on theoretical analysis, the design map… More >
