AB - Contemporary research in the field of explosive applications implies  utilization of hydrocode simulations. Validity of these simulations strongly  depends on parameters used in the equation of state for high explosives  considered. A new analytical model for determination of Jones-Wilkins-Lee  (JWL) equation of state parameters based on the cylinder test is proposed.  The model relies on analysis of the metal cylinder expansion by detonation  products. Available cylinder test data for five high explosives are used for  the calculation of JWL parameters. Good agreement between results of the  model and the literature data is observed, justifying the suggested  analytical approach. Numerical finite element model of the cylinder test is  created in Abaqus in order to validate the proposed model. Using the  analytical model results as the input, it was shown that numerical simulation  of the cylinder test accurately reproduces experimental results for all  considered high explosives. Therefore, both the analytical method for  calculation of JWL equation of state parameters and numerical Abaqus model of  the cylinder test are validated.
