description |
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. [Projekat Ministartsva nauke Republike
