The dynamic impact responses of buckyballs (from C-60 to C-720) are investigated using molecular dynamics (MD) simulations. With respect to different buckling characteristics, the fullerenes may be divided into three categories. Upon the ricochet of the impactor, the deformation of the smaller buckyballs fully recovers whereas the inverted buckling morphology of the larger buckyballs remains. Thus, energy dissipation is more prominent in the larger fullerenes, and the percentage of dissipated energy is also larger upon higher speed impact. The present study may provide some preliminary insights on employing fullerenes as advanced energy dissipation materials. (C) 2013 Elsevier Ltd. All rights reserved.
