  • By investigating the JWL equation of state of detonation products of condensed explosive, we present a method to determine JWL parameters by fitting. This approach does not require cylinder test and is more economical, secure, convenient and accurate than existing methods. Using this method, four kinds of common explosive, e.g., TNT, C-4, PETN and HMX have been studied. By comparing to the p-V curve of JWL equation of state given by cylinder test, we showed that the fitting has a high precision and meets the need of explosion mechanics application.
