Possessing excellent properties and as a promising nanofiller in nanocomposites, the mechanical properties of closed-tip carbon nanocones under tension are investigated in this paper using molecular dynamics simulation. The influence of different parameters such as apex angle, length, and number of layers on the elastic and failure properties is studied. The results indicate the significant dependence of the mechanical properties on the apex angle. Moreover, the results reveal that the Young's modulus of carbon nanocones is almost unaffected by their length and depends on the number of layers and apex angle. The transfer of load from outer to inner layers and its distribution between different layers are also investigated. It is found that the load transfer increases with increasing length and apex angle of multi-walled carbon nanocones.
