N2 - To investigate the deflagration behavior of reactive materials under multiple impacts, this study utilizes a numerical algorithm based on Autodyn to model the non-self-sustaining energy release triggered by the impact of reactive materials. By conducting numerical simulations of aluminum/polytetrafluoroethylene (PTFE) reactive material projectiles impacting aluminum alloy spacer plates with varying thicknesses, the changes in fragment morphology, as well as the temporal variations of material damage and reactivity during the impact process, were analyzed. These findings provide insights into the penetration/deflagration energy release behavior of reactive materials. The results indicate that increasing the thickness of the front plate enhances the energy release of the material in the rear plate. Furthermore, the thickness of the rear plate primarily influences the post-impact damage potential of the reactive fragments. Increasing the thickness of the rear plate leads to higher failure and reaction rates of the material during secondary impacts.
