    Notes: Nanostructured composites inspired by structural biomaterials such as bone and nacreform intriguing design templates for biomimetic materials. Here we use large scale moleculardynamics to study the shock response of nanocomposites with similar nanoscopic structural featuresas bone, to determine whether bioinspired nanostructures provide an improved shock mitigatingperformance. The utilization of these nanostructures is motivated by the toughness of bone undertensile load, which is far greater than its constituent phases and greater than most syntheticmaterials. To facilitate the computational experiments, we develop a modified version of anEmbedded Atom Method (EAM) alloy multi-body interatomic potential to model the mechanicaland physical properties of dissimilar phases of the biomimetic bone nanostructure. We find that thegeometric arrangement and the specific length scales of design elements at nanoscale does not havea significant effect on shock dissipation, in contrast to the case of tensile loading where thenanostructural length scales strongly influence the mechanical properties. We find that interfacialsliding between the composite’s constituents is a major source of plasticity under shock loading.Based on this finding, we conclude that controlling the interfacial strength can be used to design amaterial with larger shock absorption. These observations provide valuable insight towardsimproving the design of nanostructures in shock-absorbing applications, and suggest that by tuningthe interfacial properties in the nanocomposite may provide a path to design materials withenhanced shock absorbing capability
