چکیده
The use of trinitrotoluene (TNT) in industrial processes or military operations presents a significant threat to both the environment and human health due its toxicity. Recently, it has been discovered that bis(1,2,4-oxadiazole)bis(methylene) dinitrate (BOM) can be an appropriate substitute TNT low sensitivity, high detonation velocity, nearly insignificant impact on surrounding environment. In this study, we utilize molecular dynamics (MD) simulations with ReaxFF force field investigate thermomechanical chemical response BOM shock loading. We simulate shocks using Hugoniostat technique observe shock-induced, volume-expanding exothermic reactions following short induction time for strong enough insults. analyze behavior at various pressures determine conditions necessary initiate evaluate consequent events detonation. A transition between unreacted reacted materials observed several properties, such as pressure have calculated Chapman–Jouguet state. elucidate reaction initiation pathways by predicting intermediates final products reaction. quantity studied different applied loadings understand effect reactions. This study illustrates how reactive MD used characterize physics chemistry high-energy subjected loading, believe our research assist shed light numerous features may establish viable alternative TNT.
