Özet:

 In this study, the effect of additional struts added to the unit cells forming lattice structures on the mechanical properties of the structure was examined. Pyramid structure was chosen as the unit cell structure and lateral and cross support struts were added to the structure and its behavior under different loads was compared. Tensile, bending, and torsional moment loads were applied to the modeled lattice structures using the finite element method. Inconel 718, which is also frequently used in additive manufacturing, was used as the material in the analysis. As a result of the analysis, the lowest stresses were obtained under tensile load by adding cross struts to the pyramid structure, while the lowest stresses were obtained under bending and torsion loads by adding lateral struts. However, it should not be forgotten that the mass increases that occur in the lattice structure with the addition of lateral and cross struts must be considered.

 Bu çalışmada kafes yapıları oluşturan birim hücrelere eklenen ek dikmelerin yapının mekanik özelliklerine etkisi incelenmiştir. Birim hücre yapısı olarak piramit yapı seçilmiş ve bu yapıya yanal ve çapraz destek dikmeler eklenerek farklı yükler altındaki davranışları karşılaştırılmıştır. Modellenen kafes yapılara sonlu elemanlar yöntemiyle çekme, eğme ve burulma momenti yükleri uygulanmıştır. Analizlerde malzeme olarak eklemeli imalatta da sıklıkla kullanılan Inconel 718 kullanılmıştır. Yapılan analizler sonucunda piramit yapıya çapraz desteklerin eklenmesi ile çekme yükü altında en düşük gerilmeler elde edilirken, yanal desteklerin eklenmesiyle de eğme ve burulma yükleri altında en düşük gerilmeler elde edilmiştir. Ancak yanal ve çapraz dikmelerin eklenmesiyle kafes yapıda meydana gelen kütle artışlarının hesaba katılması gerekliliği unutulmamalıdır.
