At present molecular dynamics (MD) simulations are the major tools used to investigate the mechanical behaviour of fullerenes. In this study, the energy changes of three fullerene balls, C60, C80 and C 180, under uniform inflation/deflation and axial tension/compression, are investigated using the second-generation Brenner potential. The energy changes can be precisely described by a cubic function of the inflation/deflation strain or tension/compression deflection. A spherical shell, the continuum model of the fullerene balls, is established and analysed by means of non-linear elasticity theory. The results of calculations using this model are in good agreement with those of MD simulations. A regular non-linear pattern of energy change of fullerene balls subject to external loads is elucidated, and the possibility of applying continuum elasticity theories for studying shell-type nanostructures is demonstrated.
