Abstract
The influences of temperature, cone height, and apex angle on the tensile and compressive behaviors of open-tip carbon nanocones (CNCs) under axial strains were examined. The tensile failure strain and failure load of the CNC were found to decline evidently as the system temperature increases. The average failure strain decreases with the growth in the cone height. Concerning compressive behaviors, the critical strain and critical load of the CNC reduce manifestly with the increase in the system temperature and the apex angle. As the cone height grows, the critical strain decreases evidently but the critical load has no obvious change. The buckling mode does not have much variation when the temperature increases. It displays a more distorted buckling pattern with the growth in the cone height and transfers from an axisymmetric pattern to an unsymmetrical and more warped pattern when the apex angle expands.
