Abstract
To research the adsorption mechanism of oxygen and nitrogen on composition B crystal surfaces and the effect on mechanical properties and sensitivity of explosive, the crystal model of composition B was established by Material Studio (MS). The adsorption process was simulated and the mechanical properties of composition B before and after adsorption, adsorption energy of different crystal surfaces, maximum trigger bond length distribution, interaction energy of trigger bond and cohesive energy density were got and compared. The results show that the (0 1 0) crystal surface has the best adsorption capacity. The mechanical properties decrease after adsorption and it is more obvious with the increasing of adsorbed gas number, which indicates that the mechanical properties of composition B become worse. The maximum trigger bond length increases, while the interaction energy of trigger bond and cohesive energy density decrease after adsorption, thus illustrating that the sensitivity of composition B increases.
