Non-energetic reactive armors also called bulging armors are known for their effectiveness against shaped charges. These composite structures consist of two metal plates and an intermediate non-metallic layer. Soft materials like rubber or polymers are often preferred for the intermediate layer. In this paper, interaction of shaped charge jet with bulging armor is studied and the eects of material parameters of the intermediate layer are investigated by using 3d numerical simulations.

Numerical simulation of non-energetic reactive armors
Kurt, Mert Can; Gürses, Ercan; Department of Aerospace Engineering (2017)
Non-energetic reactive armors (NERAs) are one type of reactive armors which are developed to reinforce main armors of heavily armoured vehicles. Non-energetic reactive armors also called as bulging armors are known to be effective against lethal effects of shaped charges. Their structures are like sandwich structures and consist of one intermediate layer between two outer metal plates. The intermediate layer is made of inert materials such as rubber or polymers. The intermediate layer and the outer metal pl...
Ballistic penetration of hardened steel plates
Deniz, Tansel; Yıldırım, Raif Orhan; Department of Mechanical Engineering (2011)
Ballistic testing is a vital part of the armor design. However, it is impossible to test every condition and it is necessary to limit the number of tests to cut huge costs. With the intro- duction of hydrocodes and high performance computers; there is an increasing interest on simulation studies to cutoff these aforementioned costs. This study deals with the numerical modeling of ballistic impact phenomena, regarding the ballistic penetration of hardened steel plates by 7.62 mm AP (Armor Piercing) projectil...
Alloy design for the development and production of titanium based bulk metallic glasses
Demir, Iraz Begüm; Akdeniz, M. Vedat.; Department of Metallurgical and Materials Engineering (2019)
The bulk metallic glasses (BMGs) are quite new type of metallic alloys exhibiting many superior features like high yield strength, improved elastic behavior, high corrosion resistance and superior abrasion resistance by virtue of its irregular atomic structures. Due to the importance of today’s reduced energy consumption, special attention is given to the light element-based bulk metallic glasses. Among these, Ti-based amorphous alloys have promising mechanical properties for use in engineering applications...
Nanolayered metallic glass-crystalline composites with high strength and wear resistance
Özerinç, Sezer (null; 2020-02-23)
Nanolayered metallic glass-crystalline composites are promising materials that combine the high strength of metallic glasses with the superior ductility of crystalline metals. Previous work has focused on metallic glass-FCC crystalline nanolayers, and showed that the strength follows the Hall-Petch behavior of increasing strength with decreasing layer thickness. In our work, we investigated metallic glass-HCP crystalline nanolayers. Interestingly, the strength of these layers does not show any size effect; ...
Micromechanically Motivated Modeling of Semicrystalline Polymers
Oktay, Hasan Emre; Gürses, Ercan; Göktepe, Serdar (2017-09-05)
Semicrystalline polymers (SCPs) are of ever increasing technological importance due to their remarkable toughness, good impact strength, very low gas-permeability, superior wear resistance, and biocompatibility. They have been used in applications such as ballistic plates, model aircraft, liquid and gas containers, plastic bags, piping systems, electrical insulation systems, substrates for flexible electronic devices, and joint implants. Owing to amorphous polymer chain networks and crystalline structures, ...
