Özet:Explosives are energetic materials which are used for various military or civilian purposes. Several computer programs are used for predicting the behaviour of systems containing explosives. During modeling of various explosives in simulation software, Jones-Wilkins-Lee equation of state is widely used. However, the parameters used in JWL equation of state are not available for some of the explosives in open sources. A method called cylinder expansion test is used in order to determine these parameters. In this thesis study, a cylinder expansion test setup was designed and developed. Cylinder expansion tests were performed for four different types of explosives employing the designed setup and JWL equation of state parameters were obtained for these explosive compositions using the data gathered from the tests. Two tests were performed for each explosive. Two of the explosives selected were conventional explosive compositions with equation of state parameters available in the literature. Pressure versus specific volume ratio curves for these explosives were obtained using the JWL equations determined via the tests. The curves obtained via the tests results were compared with the curves based on the literature data and it was concluded that the results were close enough. The other two explosives used in the tests were newly developed compositions with no JWL equation data available in the literature. JWL equation of state parameters for these explosives were also obtained successfully.
