title = "NUMERICAL SIMULATION OF THE CLOSED VESSEL TEST FOR GUNPOWDER BALLISTIC PARAMETERS STUDY",
abstract = "The aim of this paper is to present a numerical model for the closed vessel test (CVT) developed under the FEA software MSC-Dytran and a mathematical algorithm implemented using FORTRAN and Python codes to determine and improve the burning rate parameters of the gunpowder. First, the ballistic parameters of the investigated double-base deterred gunpowder such as co-volume, force and vivacity were calculated according to STANAG 4115 based on the pressure-time data obtained from a CVT at the ballistics laboratory of the Military Academy. Then, these parameters were used in the numerical simulations conducted based on an equation of state available in the FEA software MSC-Dytran. The burning rate parameters according to the Vieille{\textquoteright}s Law were improved by fitting gradually the simulated to the experimental pressure using a dedicated reverse computing algorithm. The obtained results from several Finite element analysis have confirmed the reliability of the developed numerical model and the implemented algorithm, especially since they allow giving an excellent view and a reasonable description of the experimental closed vessel test.0F 1F 2F 3F.",
