Laminated composite armors provide significant advantages to the defense systems when considering both the mobility and energy consumption. Among them, alumina faced laminated composite systems have been considered as strong candidates due to their relatively low cost and availability. In this study, the ballistic response of alumina/4340 steel laminated composites was investigated under the impact of 7.62 mm armor piercing (AP) projectiles. The influence of the mechanical properties of the steel backing layer and the areal density on the ballistic performance of these composites was examined. Experimental results showed that the best ballistic protection was found for the composites having the steel backing layer of 40 or 50 HRC (Hardness Rockwell C).

Effect of Hardness on the Ballistic Impact Behavior of High-Strength Steels Against 7.62-mm Armor Piercing Projectiles
DEMİR, TEYFİK; Ubeyli, Mustafa; Yıldırım, Raif Orhan (2009-03-01)
Ballistic performance of engineering materials should be known in selection of the most suitable armor material to protect civilian or military system with the lowest possible weight against various threats. In this study, the ballistic impact characterization of high-strength steels, namely AISI 4340 and DIN 100Cr6, was investigated using 7.62-mm armor piercing (AP) projectiles by considering four hardness levels and five areal densities. The main aim was to examine the effect of hardness and areal density...
Ballistic impact performance of an armor material consisting of alumina and dual phase steel layers
Ubeyli, Mustafa; Deniz, Huseyin; DEMİR, TEYFİK; Ögel, Bilgehan; Gurel, Bayram; KELEŞ, Ömer (2011-03-01)
Utilization of a ceramic front layer provides an improvement in the ballistic efficiency of monolithic metallic materials. In the current paper, the ballistic behavior of laminated composite having alumina front and dual phase steel backing layers was studied using 7.62 mm armor piercing (AP) projectiles under normal impact. The variables used were martensite content of the backing layer and the areal density of the composite. Experimental results showed that utilization of a 6 mm thick alumina front layer ...
Turbulent flow and acoustic predictions over open cavity configurations at transonic speeds
Çoşkun, Seyfettin.; Özyörük, Yusuf; Department of Aerospace Engineering (2019)
In modern military fighters, internal carriage of weapons is vital in terms of high survivability, low observability and aerodynamic performance of the fighter. During store release phases of operation, the aircraft will have to fly with the cavity exposed to free stream conditions. When an aircraft internal weapons bay is exposed to free stream of air, a highly unsteady and complex flow field develops within the cavity. This triggers intense aero-acoustic environment in and around the cavity. Highly complex, un...
Assessment of the Effect of Hybrid GFRP CFRP Usage in Wind Turbine Blades on the Reduction of Fatigue Damage Equivalent Loads in the Wind Turbine System
Gözcü, Ozan; Farsadi, Touraj; Şener, Özgün; Kayran, Altan (null; 2015-01-05)
The use of hybrid GFRP-CFRP material in wind turbine blades is investigated for its effectiveness in reducing fatigue damage equivalent loads in the whole wind turbine system, and comparisons are made against the baseline full GFRP blade in terms of strength, deformation, dynamic characteristics, weight and cost of the blade. To achieve load alleviation in the whole wind turbine system, bending-twisting coupling in composite blades is exploited through the use of off-axis plies in the spar caps of the blade...
Investigation of Simulated Ground Penetrating Radar Data for Buried Objects Using Quadratic Time-Frequency Transformations
DOĞAN, MESUT; Sayan, Gönül (2017-07-14)
Sub-surface sensing is a challenging area of research that highly benefits from the use of ultra-wideband ground penetrating radar (GPR) technology. Detection and classification of buried objects with reduced false alarm rates is still open to improvements. Use of joint temporal and spectral target features obtained from electromagnetic GPR signals using time-frequency representation (TFR) methods is highly promising because TFRs provide detailed information about the energy distribution of GPR signals over...
