An overview of the mechanical properties of foams and periodic lattice materials

摘要

Metallic foams and lattice materials are compared in terms of properties and underlying deformation mechanisms. Lattice materials can be made to possess mechanical properties which are similar to, or exceed, those of foams depending upon the nodal connectivity. Scaling laws are reviewed here for the Young's modulus and yield strength of foams and lattice materials, and the damage tolerance of each class of material is discussed.
