The electron irradiation effects in carbon nanomaterials are studied by the molecular dynamics simulation including the elastic collision between an incident electron and a carbon atom. The scattering angle of the incident electron is determined using the screened Rutherford cross section. The transferred energy from the electron to the carbon atom and the scattering angle of the carbon atom are obtained by the binary collision theory. The structural changes in the single-walled carbon nanotube, double-walled carbon nanotube, graphite and C60 peapod by the electron irradiation are calculated with the simulation.
