Molecular Dynamics Study of the Specimen Size and Imperfection Effects on the Failure Responses of Multi-Nanobar Structures

RESUMO
Based on the recent analytical and numerical studies of the size effect on the structural failure response of bar members in parallel arrangement at the macroscopic level, molecular dynamics simulations are performed to investigate the effects of size, imperfection, and number of nanobars on the failure mechanism of nanoscale hierarchical structures with one-dimensional members arranged in parallel. It appears that at the nanoscale the possibility of being in the stable softening regime increases with the decrease of nanobar length, and the energy dissipation associated with the postlimit softening regime increases with the increase of the number of nanobars in the system, regardless of imperfection types. The results obtained at the nanoscale not only match well the analytical and numerical predictions at the macroscopic level, but also provide more insight into the effects of imperfections on the postlimit structural response.
