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.

Modeling and simulation of shaped charges Gürel, Eser; Sert, Cüneyt; Department of Mechanical Engineering (2009) Shaped charges are explosive devices with a high penetration capability and are used for both civilian and military purposes. In civilian applications shaped charge devices are used in demolition works, oil drilling and mining. In the military applications, shaped charges are used against different kinds of armors, primarily as anti-tank devices. This thesis work involves the modeling and simulation of shaped charge devices, with the focus being on anti-tank warhead design. Both numerical simulation and ana...
Effect of liner material and explosive type on penetration effectiveness of shaped charge Zaki, S.; Uddin, Emad; Rashid, B.; Mubashar, A.; Shah, Samiur R. (2019-07-01) Shaped charges are used in many civilian and military applications. This study focuses on the effects of liner material and the type of explosive on the development of shaped charge jet. This was carried out by experimentation and numerical finite element-based modelling. Shaped charges were tested on a steel plate during the experimentation and the experimental data were used to validate the developed numerical model of the shaped charge. A hydrocode-based finite element model was able to predict the perfo...
Investigation of Acoustic Source Localization algorithm performances for Gunshot Localization on helicopters Yılmaz, Murat; Günel Kılıç, Banu (2016-06-23) Self-defense solutions on current aircraft usually handle advanced weapons while most helicopters down or damaged are known to be attacked from ground using rifles or Rocket-Propelled Grenades (RPG). Although there are ground based localization solutions for Small Arms Fire (SAF) attacks, there are only a few implementations of onboard applications. A simple Acoustic Source Localization (ASL) application employs a microphone array for collecting audio signals, so as to locate sound sources using the measure...
Combination of physics-based and image-based features for landmine identification in ground penetrating radar data Genc, Alper; Akar, Gözde (SPIE-Intl Soc Optical Eng, 2019-4-23) Ground penetrating radar (GPR) is a powerful technology for detection and identification of buried explosives, especially with little or no metal content. However, subsurface clutter and soil distortions increase false alarm rates of current GPR-based landmine detection and identification methods. Most existing algorithms use shape-based, image-based, and physics-based techniques. Analysis of these techniques indicates that each type of algorithm has a different perspective to solve the landmine detection a...
A REVIEW OF POLYCYCLIC AROMATIC ENERGETIC MATERIALS Türker, Burhan Lemi; Varis, Serhat (2009-01-01) Explosives are employed extensively not only in military areas but also in civilian applications. There are many researchers working on the discovery of explosives. In recent years, synthetic and theoretical studies on polycyclic aromatic explosives have received significant interest. The present short review concentrates on the synthesis and some of the physico-chemical characteristics of energetic materials of the classes of tetraazapentalene, naphthalene, di-and tetraaza-naphthalene, pyrazolo-pyrazole, b...
