The ballistic performance of SiC-AA7075 functionally graded composite produced by powder metallurgy ÜBEYLİ, MUSTAFA; BALCI, ERHAN; Sarikan, Bertan; ÖZTAŞ, MURAT ORHAN; CAMUŞCU, NECİP; Yıldırım, Raif Orhan; KELEŞ, Ömer (2014-04-01) The potential of silicon carbide reinforced Functionally Gradient Material (FGM) to be used as armor material was investigated under the impact of armor piercing projectile. For this purpose, the SiC-Aluminum Alloy (AA) 70...
BALLISTIC PENETRATION OF HARDENED STEEL PLATES Deniz, T.; Yıldırım, Raif Orhan (2013-04-26) The change in ballistic performance of AISI 4340 steel plates with different thicknesses and varying hardness against 7.62 AP (Armor Piercing) projectiles is studied. Four different target plate hardnesses are chosen. The ...
On the ballistic performance of the AA7075 based functionally graded material with boron carbide reinforcement Balci, E.; Sarikan, B.; ÜBEYLİ, MUSTAFA; CAMUŞCU, NECİP; Yıldırım, Raif Orhan (2013-01-01) In this study, the functionally graded materials (FGMs) bearing three layers were produced via hot pressing to investigate their ballistic performances against 7.62 mm armor piercing (AP) projectile. In the FGM samples, th...
DETRIMENTAL EFFECTS OF FLEXIBLE LINEAR SHAPED CHARGE (FLSC) TO NEARBY PLATES DUE TO VARYING BACKSPACE DISTANCE Bingol, C. G.; Yıldırım, Raif Orhan (2011-09-16) The objective of this study is to investigate the detrimental effects of a flexible linear shaped charge (FLSC) to variable thickness (3, 4 and 5 mm) Raex Ar 400 back plate and constant thickness (4.8 mm) Al-6061-T6 front ...
Investigation of the effect of thickness and radius of curvature on explosively formed penetrator (efp) formation Bingol, C.G.; Yıldırım, Raif Orhan (2010-12-01) In this work, a numerical study is carried out by using AUTODYN hydrocodc for the investigation of the effects of thickness and radius of curvature of the liner on the formation of Explosively Formed Penetrator (EFP). It i...
Investigation on the ballistic performance of a dual phase steel against 7.62 mm AP projectile Ubeyli, Mustafa; DEMİR, TEYFİK; Deniz, Hueseyin; Yıldırım, Raif Orhan; KELEŞ, Ömer (2010-03-25) Dual phase steels have the potential to reduce the weight of structural components because of the improved mechanical properties obtained from the two phases: soft ferrite and hard martensite. In this study, the ballistic ...
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,...
