The Young’s Modulus of Single-Walled Carbon Nanotubes
Abstract
A new numerical method for calculating the Young’s modulus of carbon nanotubes which avoids ambiguities that have plagued other attempts is validated. Molecular dynamics simulations that utilize the Tersoff Potential are used to model various single-walled carbon nanotubes under different strains to achieve this validation. Data is taken from an armchair, zigzag, and chiral carbon nanotube. The calculated Young’s moduli are all around Y = 1 TPa, in agreement with existing experimental data.
