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

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...
