Abstract :
The finite-difference time-domain and molecular dynamics method are coupled in both spatial and temporal dimensions to predict mechanical, thermodynamic, electromagnetic properties, and dynamic behaviors of nanoscale materials/devices in complex electromagnetic fields on atomic level. Using the proposed method, impact processes of carbon nanotubes in electromagnetic field are simulated, and the dynamic cracking process is obtained. Finally the structural stability of nanotubes is discussed
