From: Nonlinear vibration of a buckled/damaged BNC nanobeam transversally impacted by a high-speed C60

FFT results of yo*(t) curves with respect to different incident velocities. (a) Vibrations of the beam in the yz-plane when vIn = 35Å/ps and 55Å/ps, respectively. (b,c) Results of FFT in the time interval of [200, 2200] ps.
