Natural cellular materials—e.g., bone, wood, and honeycomb—are known for their extraordinary mechanical performance such as strength-to-weight and damage tolerance. One of common geometrical features of these natural cellular materials is their Voronoi-like structure, which has been demonstrated as a critical mechanism to improve mechanical performance by studies in recent decades. Inspired by these interesting structures, scientists and engineers have developed Voronoi-like mechanical metamaterials with tunable mechanical properties for various industrial applications. However, most studies focus on designing fully random or fully ordered Voronoi-like structures, which are not common in Nature. Moreover, natural materials also show hierarchy in Voronoi-like designs. Therefore, to fill this knowledge gap and develop tunable architectures, an algorithm which controls the finite randomness of Voronoi-like structures and achieves associated hierarchical design has been elaborated.
