“…The aluminium is compared with the steel and found to be better than steel based on projectile perforation resistance [8]. While coating of the provides better resistance to the impact projectile thus ductile hole is reduced [10]. For magnesium alloy, AZ31B , it is light weight and has more resistance to projectile impact than the other magnesium alloy, hence it is suited for ballistic operation [1].…”

“…Rodriguez-Millan et al [3] compared the ballistic limit of AA 5754-H111 and AA6082-T6 plates and found out the AA5754 is efficient than AA6082-T6, when the conical and hemispherical projectiles while the behavior is opposite for blunt projectiles. Evren Ozsahin et al [10] researched the application of coatings on the aluminium for better ballistic performances. Penetration depth is found to appear on the coated alloy with bulging on the rear side making it ballistic efficient than the uncoated alloy especially at the higher impacts such as 390 m/s and higher due to presence of Co-Mo-Cr coatings rather than the Zirconium.…”

A recent development in the material studies provides beneficial application of lightweight alloys such as aluminium, magnesium as well as composites and metal matrices. The alloys are experimentally improved by increasing hardness in the ballistics testing using projectiles, makes them viable for the areas such as aerospace, military, defence, automobiles and so on. So the study is made on different approaches. First, by comparing different types of non-ferrous alloys and projectiles regarding sizes, structures. Second, the materials with heat treatment are also studied for investigating the hardness property by overcoming successful penetration on non-ferrous alloys. Third, material to be improvised by use of numerical studies such as 3D models, empirical models and software such as ANSYS, ABAQUS and AUTODYN, etc. Finally, the aim of this paper is to review the recent progress ballistic studies of lightweight materials and to provide a best choice of material for further ongoing research.

“…Fiber/epoksi katmanda kullanılan fiber miktarının artmasının ise darbe direncini arttırdığı yine literatürde belirtilmiştir [62]. FML'lerde kullanılan metal malzemelere kaplama yapılarak ta malzemenin darbe direnci arttırılabilmektedir [63]. Metal ve elyafların yapışma kuvveti de FML'lerin darbe direncini etkileyen önemli bir parametredir.…”

Günümüzün rekabetçi havacılık ortamında, yüksek performanslı ve hafif uçakların tasarlanması, üretilmesi ve bu kapsamda, yeni üretim metodlarının ve yeni üretim malzemelerinin kullanılması önem arz etmektedir. Bu amaçla, Delft Üniversitesi tarafından geliştirilen Fiber metal laminatlar (FML), yüksek yorulma dirençlerinden dolayı, uçaklarda kullanılan geleneksel alüminyum malzemelere alternatif olarak kullanılabilecek özel kompozit malzemelerdir. Bu çalışmanın amacı FML'lerin tarihçesi, kullanım alanları, çeşitleri ve özellikleri (statik, yorulma, darbe, korozyonve ısı dayanımı) hakkında geniş bir literatür özeti sunmak ve ilerde yapılabilecek çalışmalar hakkında fikir vermektir.

“…Several researchers have conducted experimental, theoretical, and numerical studies on the ballistic response of aluminium 7xxx grades to high impact velocity projectiles. [7][8][9][10][11][12][13][14][18][19][20][21][22][23] Mishra et al 7 studied the ballistic performance of various heat treated AA7055 plates against high velocity projectile impact. They reported that peak aged AA7055 aluminium alloy plates exhibited better ballistic performance compared to under and over aged AA7055 plates because of improved tensile properties and surface hardness.…”

The influence of target thickness and solution treatment on the ballistic behaviour of AA7075 targets has been investigated by both numerical and experimental methods. In numerical simulation, the target thickness was varied from 19 to 26 mm and an Ogive nose shaped projectile of 7.62 mm diameter with inlet velocities ranging between 800–875 m/s was considered. In order to justify the numerical observations, high velocity ballistic experiments were conducted on AA7075-T651 and the solution treated plates of various thicknesses (12, 16, 18, 20, 22 and 25 mm). For this experimental study, a deformable form projectile with dimensions of 7.62 × 51 mm and an inlet velocity of 850 ± 20 m/s was used. Microstructures of ballistic test samples were analysed using an optical microscope. Numerical analysis using ABAQUS predicted the minimum thickness required to resist complete penetration to be 20 mm in the case of AA7075 plates in the T651 condition, while experimental results showed it to be 21 mm. In the case of AA7075 solution treated plates, numerical simulation analysis predicted the minimum required plate thickness to resist complete penetration to be 24 mm, while the experimental results showed it to be 23 mm. Post ballistic microstructure analysis revealed that there was no change in the microstructure in the AA7075-T651 condition plates. Solution treated plates showed deformation of grains nearer to the impact region with the formation of adiabatic shear bands. In the case of the T651 plate, the mode of fracture was brittle, resulting in splinters, whereas it was petalling in the case of the solution-treated plates. The numerically predicted depth of penetration on both targets was reasonably close to experimental results with an average of 4% error.
