中文摘要：
An analytical method is presented to fit parameters of Jones-Wilkins-Lee(JWL) equation of state(EOS) for the chemical process of aluminum-polytetrafluoroethylene(Al/PTFE) mixture.Subroutine codes for both strength model and EOS were developed in explicit-FE code AUTODYN.Firstly,the shock Hugoniot data of reactive Al/PTFE mixture was analytically derived by implementing this methodology.The JWL EOS was verified to fit shock Hugoniot data of both reacted and unreacted Al/PTFE mixture,which gives reasonable results.Furthermore,to numerically ascertain the reaction phases of ignition and growth and quasi detonation of Al/PTFE mixture,characterized experiment was setup to validate the reaction phases and coefficients of JWL EOS for Al/PTFE mixture.From the test,a promising example of reactive mixture Al/PTFE is capable to enhance lethality of weapons,the status computation in clude quasi-detonation pressure and temperature of Al/PTFE mixture in different chemical reaction phases is validated.
英文摘要：
An analytical method is presented to fit parameters of Jones-Wilkins-Lee （JWL） equation of state （EOS） for the chemical process of aluminum-polytetrafluoroethylene （ AI/PTFE ） mixture. Subroutine codes for both strength model and EOS were developed in explicit-FE code AUTODYN. Firstly, the shock Hugoniot data of reactive A1/PTFE mixture was analytically derived by implemen- ting this methodology. The JWL EOS was verified to fit shock Hugoniot data of both reacted and un- reacted A1/PTFE mixture, which gives reasonable results. Furthermore, to numerically ascertain the reaction phases of ignition and growth and quasi detonation of A1/PTFE mixture, characterized ex- periment was setup to validate the reaction phases and coefficients of JWL EOS for A1/PTFE mix- ture. From the test, a promising example of reactive mixture A1/PTFE is capable to enhance lethality of weapons, the status computation in clude quasi-detonation pressure and temperature of A1/PTFE mixture in different chemical reaction phases is validated.
