Young's Modulus of Single and Double Walled Carbon Nanocones Using FiniteElement Method

In this paper, a three-dimensional finite element (FE) model of carbon nanocones (CNCs) is proposedand used for obtaining Young's modulus of CNCs. In this model, stretching and bending forcesbetween carbon atoms are simulated using truss elements in ANSYS software. Then, the model issubjected to the tension and by obtaining the stiffness of the CNC and using elasticity theory, Young’smodulus is calculated. The results showed that for a fixed length of CNC, the modulus increase withthe increase in diameter whereas it decreases by an increase in the apex angle. Also, Young’s modulusof double walled carbon nanocones (DWCNCs) obtained between the values of each layer.Furthermore, it is showed that elastic modulus can be effected by defects and their positions in CNC.
