Lattice mechanical metamaterials have received a great deal of attention due to their extraordinary mechanical properties. Metamaterials based on bending-dominated structures, particularly BCC metamaterials, have been reported to exhibit high specific energy absorption, but lower stiffness and strength. Here, we report the effect of increasing heterogeneity in BCC lattice materials computed using a stochastic mechanical modeling approach previously applied to open-cell foam structures. Distributions of computed properties also reveal details of the transition from micro- to meso-scale (bulk-like) behavior and the expected variability in observed mechanical responses.
