Overview of Methods and Software for the Design of Functionally Graded Lattice Structures

“…Savio et al [ 22 ] proposed a classification scheme based on the geometry of cellular materials according to four principal criteria: cell element dimensions, cell geometry, cell topology, and structure shape. Zok et al [ 23 ] created a phylogenetic tree of truss‐based lattices, starting from the elementary cubic structures and increasing their complexity into further levels of classification. As illustrative cases, two different lattice classifications are depicted in Figure .…”

“…According to Zok et al, [ 23 ] the network topology of a lattice structure is defined by a set of connectivity rules without precise node locations (Figure 5l), top row), and the network morphology is determined by the relative locations of the nodes, which influence strut lengths and angles (Figure 5l), bottom row). Latticing can be done at different hierarchical levels (Figure 5m), or with varying topologies (Figure 5n).…”

Simulation of the behavior of lattice structured impact absorbers manufactured by additive manufacturing

“…In essence, cellular material presents structure behavior at a small‐scale and homogeneous material behavior on macroscopic scale 5 . The control of material structure is an important factor that can lead to outstanding mechanical properties, such high strength, elevated EA, lightweight, ultra‐high damping capacity, and negative Poisson ratio 5–7 …”
