Abstract
Advancements in metal additive manufacturing have enabled the production of metal lattice structures. The customizability of the lattice topology offers the potential to yield lightweight materials with highly tailored thermal and mechanical properties. By building on well-established models of other cellular solids such as metal foams, the intricate structural behavior of these lattices is simplified to effective values for key mechanical properties which are given as a function of the relative density of the lattice as well as certain material and lattice parameters. It is intended that these effective values will be used to represent the lattice at a macroscopic level, vastly reducing the complexity of the models needed to simulate the material for design applications. The study investigates the compressive modulus of lattice structures with a particular emphasis on the impacts of the cell topology and dimensions of the unit cell elements.
