Abstract
To investigate the shear ignition mechanism of solid explosives, the node tie-breaking approach, the thermo-elastic-plastic material model and the chemical kinetics equation were used to simulate the shear ignition of TNT and PBX-C03. The critical impact velocities of shear ignition and the shear destruction behaviors of TNT and PBX-C03 were obtained. The results indicate that the node tie-breaking approach, the thermo-elastic-plastic material model and the chemical kinetics equation are promising for simulating the ignition of solid explosives and coupled thermal-mechanical-chemical effect under mechanical stimuli.
