| Abstract: | Molecular dynamics simulation was applied to investigate the mechanical properties of nitroglycerine (NG) and mixed nitrate plasticizers which composed of nitroglycerine and triethylene glycol dinitrate (TEGDN) at low temperature. It was shown that the rigidity was weakened, the ductibility and isotropies were improved by adding TEGDN. By calculating binding energy and pair correlation function, the interface interaction and its essence of the nitrate plasticizer were elucidated. |
| Keywords: | nitrate plasticizer molecular dynamics mechanical property binding energy pair correlation function |
