Determination of detonation products equation of state using cylinder test

Abstract

Contemporary research in the field of explosive applications implies utilization of „hydrocode“ simulations. Validity of these simulations strongly depends on used parameters in the equation of state for considered explosive compounds. A new analytical model for determination of Jones-Wilkins-Lee (JWL) equation of state parameters based on cylinder test has been proposed. The model relies on analysis of cylinder motion and detonation products expansion. Available cylinder test data for five explosive compositions are used for calculation of JWL parameters. Good compatibility between results of the model and the literature data is observed, justifying suggested analytical approach.
