Influence of surface atomic structure on the mechanical response of aluminum nanospheres under compression
Computational Materials Science(2017)
Abstract
•Compressed Al nanospheres plastically deform by dislocation nucleation.•These dislocations are Shockley partials forming at surface contact edges.•The contact surface structure controls the plasticity, not the nanoparticle size.•Models available in literature are not applicable.
