Kafes Yapılarla Pekiştirilmiş Kompozit Plakanın Serbest Titreşim Analizi

Farklı kafes yapıları ile pekiştirilmiş tabakalı kompozit plakaların serbest titreşim davranışı incelenmiştir. Serbest titreşimi simüle etmek için, Ansys Parametric Design Language (APDL) ile sonlu eleman modelleri oluşturulmuştur. Modellerde tabakalı kompozit ve kafes yapıların modellenmesinde sırasıyla SHELL181 ve BEAM181 elemanları kullanılmıştır. Farklı pekiştirici kafes yapılarının kompozit plakanın doğal frekansları üzerindeki etkisi, ankastre-serbest-ankastre-serbest sınır koşulu için incelenmiştir. Sonuçlar, L2 tipi kafesten yapılan pekiştirilmiş kompozit yapıların frekans parametrelerinin diğer kafes tiplerinden oluşanlardan daha yüksek olduğunu göstermiştir. Bu çalışma, kafes yapılarının kompozit plakalar için pekiştirici yapıları olarak kullanımına ilişkin bilgimizi artırmak için ilgi çekici bir fırsat sunmaktadır.

Free Vibration Analysis of Composite Plate Stiffened by Lattice Structures

Free vibration behavior of laminated composite plates stiffened by different lattice structures is considered. To simulate free vibration, finite element models were created with Ansys Parametric Design Language (APDL). In the models, SHELL181 and BEAM181 elements were used to model laminated composite and lattice structures, respectively. The influence of the different stiffeners lattice structures on natural frequencies of the composite plate is examined for the clamped-free-clamped-free boundary condition. The results showed that the frequency parameters of the stiffened composite structures made of the L2-type lattice are higher than those composed of other lattice types. This study provides an exciting opportunity to advance our knowledge of the usage of lattice structures as stiffener structures for composite plates.
