In order to study the differences between shock initiation reaction flows of HMX-based and TATB-based plastic bonded explosives and the detonation growth characteristics of non-ideal plastic bonded explosives,Lagrange analysis method is used to calculate the reaction flow variables of PBXC 03( mainly HMX) and PBXC 10( mainly TATB). Pressure history curves obtained from experiment are used as the input variables. Particle velocity,relative specific volume and specific internal energy obtained from integrating conservation equations by constructing the path lines. Through comparison of reactive flows of PBXC 03 and PBXC 10 explosives,the results show that the particle velocity of PBXC10 explosives is not obviously increased after the shock wave front. This indicates that the physical mechanisms of the shock initiation and detonation growth of TATB-based plastic bonded explosives are different from those of HMX-based plastic bonded explosives.
