Fracture resistance of zigzag single walled carbon nanotubes
Qiang Lu, Baidurya Bhattacharya
Brittle fracture is one of the important failure modes of Single-Walled Carbon Nanotube (SWNT) due to mechanical loading. In this paper, the fracture resistance of zigzag SWNTs wit…
Effect of randomly occurring Stone-Wales defects on mechanical properties of carbon nanotubes using atomistic simulation
Qiang Lu, Baidurya Bhattacharya
While CNTs are found to have ultra high stiffness and strength, an enormous scatter is also observed in available laboratory results. This paper studies the effects of randomly dis…
Effect of edge structures on elastic modulus and fracture of graphene nanoribbons under uniaxial tension
Qiang Lu, Rui Huang
Based on atomistic simulations, the nonlinear elastic properties of monolayer graphene nanoribbons under quasistatic uniaxial tension are predicted, emphasizing the effect of edge…
Excess energy and deformation along free edges of graphene nanoribbons
Qiang Lu, Rui Huang
Change of the bonding environment at the free edges of graphene monolayer leads to excess edge energy and edge force, depending on the edge morphology (zigzag or armchair). By usin…
Elastic Bending Modulus of Monolayer Graphene
Qiang Lu, Marino Arroyo, Rui Huang
A new formula for elastic bending modulus of monolayer graphene is derived analytically from an empirical potential for solid-state carbon-carbon bonds. Two physical origins are id…
