(a) Compressive modulus vs density for different
lightweight materials
families and comparison with the studied lattices (SC, BCC, and FCC).
(b) Relative compressive elastic modulus (i.e., the measured compressive
elastic modulus of the lattice divided by the compressive elastic
modulus of the constituent solid) of the studied 10 × 10 ×
10 lattices as a function of the relative density and comparison with
foams and honeycombs. The two trendlines approximate the different
behavior of honeycomb and foams. Data related to the lattices studied
in this paper refer to numerical simulations. Data for foams, honeycombs,
and bone are taken from the CES Edu Pack database.
