This study examines the bending behavior of single-layer armature-type graphene nanoplates of varied diameters due to variable-distribution atomic vacancy defects. This study is novel because it thoroughly examines the effects of aspect ratio, defect concentration, clamped-free (CF), clamped-clamped (CC), and simply-supported (SS) boundary conditions on graphene nanoplate buckling. Novel space frame structures were employed to characterize nanoplates to preserve their discreteness. The finite element approach anticipated buckling. The simulation results for the critical buckling load (Pcr) were confirmed by comparing them to accessible literature data. Results show that reducing this factor significantly decreases Pcr at low aspect ratios, whereas the loss becomes slow at higher aspect ratios. Research indicates that atomic-scale errors considerably reduce Pcr, with a 10% concentration resulting in a 40% drop in critical buckling stress, highlighting the significance of defects in nanostructure stability.
