Metal eklemeli imalat teknolojisi ile üretilen kafes yapılar, şok dalga sönümleme, enerji emme ve hafiflik özellikleri nedeniyle savunma teknolojilerinin önemli bir parçası olan zırh uygulamalarında potansiyel bir alternatif olabilirler. Metal kafes yapıların patlayıcılara karşı korunması literatürde sıklıkla araştırılmış olmasına rağmen, perforasyon performansları nadiren çalışılmıştır. Bu araştırmada, LS-DYNA yazılımı kullanılarak Johnson-Cook dayanım ve hasar modeli parametreleri ile sayısal balistik penetrasyon testleri gerçekleştirilmiştir. Kafes malzemesi olarak yüksek enerji soğurma kabiliyetine sahip AlSi10Mg alaşımı seçilmiştir. Hacim merkezli kafes yapı için hem genişlik hem de uzunluk 4 mm olarak seçilirken, birim hücre parametreleri olarak sekiz farklı hücre yüksekliği (3, 4, 5, 6, 7, 8, 9 ve 15 mm) kullanılmıştır. Sonuçlar, kafes yapılarının balistik performansının, hacim merkezli kafes yapılar için birim hücre yüksekliğinin optimize edilmesiyle geliştirilebileceğini göstermektedir.

Effect of Unit Cell Height on the Ballistic Performance of the Body-Centered Lattice Structures

Öz

Lattice structures, produced by metal additive manufacturing technology, can be a potential alternative in armor applications, which are important parts of defense technologies due to their shock wave damping, energy absorption and light-weight properties. Despite the fact that the protection of metal lattice structures against explosives has been frequently investigated in the literature, their perforation performance is rarely studied. In this research, numerical ballistic penetration tests were carried out with Johnson-Cook strength and failure model parameters by using LS-DYNA software. AlSi10Mg alloy was chosen as a lattice material, which has high energy absorption ability. Both width and length were chosen as 4 mm for the body-centered lattice structure, while eight different cell height (3, 4, 5, 6, 7, 8, 9 and 15 mm) were used as unit cell parameters. The results show that the ballistic performance of lattice structures could be improved by optimizing the unit cell height for the body-centered lattice structures.
