Modeling of Impact Energy Release of PTFE/Al Reactive Material

Many scholars have used experimental research methods to conduct extensive on the impact energy release behavior of Polytetrafluoroethylene(PTFE)/Al reactive materials. However, in numerical simulation, PTFE/Al still lacks calculation parameters behavior. In order obtain simulation ignition, Hill mixture law was calculate material (mass ratio 73.5/26.5), and according Hugoniot curve γ state equation, JWL equation a unreacted substance reaction product fitted with genetic algorithm. According experiment, chemical kinetic were determined, trinomial rate fitted. The obtained LS-dyna predict damage aluminum target plate under fragments.
