Mechanical response of face-centered cubic metallic nanospheres under uniaxial compression

摘要

Nano-objects often exhibit drastically different properties compared to their bulk counterpart, opening avenues for new applications in many fields, among which advanced composite materials, nanomanufacturing, or nano-electromechanical systems. For instance, it has been recently shown that nanowires exhibit enhanced mechanical properties. The literature regarding the plastic deformation of a single nanoparticle is more recent and more limited. In this study, we have performed molecular dynamics simulations to investigate the mechanical behavior of metallic nanoparticles.
