Abstract:

 Layered composite sandwich elements are used extensively in many industries such as construction, automotive, aviation and marine. Due to their advantageous properties such as high strengthweight ratio, non-abrasive, good surface, etc., the use of these materials is intensely preferred and the studies on these materials are increasing day by day. In this study, modal analysis of laminated composite sandwich plate was performed. In the analyses, the finite element model was created using ANSYS and ABAQUS programs. Natural frequencies were obtained by performing free vibration analyzes in various layering conditions of the laminated composite sandwich plate. It is seen that the fiber angles, layer array order and boundary conditions have an effect on the natural frequencies and mode shapes of the laminated composite honeycomb sandwich plate.

 Tabakalı kompozit sandviç elemanlar, inşaat, otomotiv, havacılık ve denizcilik gibi birçok sektörde yoğun bir şekilde kullanılmaktadır. Yüksek mukavemetağırlık oranı, aşındırıcı olmayan, iyi yüzey vb gibi avantajlı özelliklere sahip olmalarından dolayı bu malzemelerin kullanımı yoğun olarak tercih edilmekte ve bu malzemelerle ilgili yapılan çalışmalar günden güne artmaktadır. Bu çalışmada, tabakalı kompozit sandviç plağın modal analizi yapılmıştır. Analizlerde, sonlu elemanlar modeli, ANSYS ve ABAQUS programları kullanılarak oluşturulmuştur. Tabakalı kompozit sandviç plağın çeşitli tabakalanma durumlarında serbest titreşim analizleri yapılarak doğal frekanslar elde edilmiştir. Elyaf açılarının, tabaka dizilim sırasının ve sınır koşullarının tabakalı kompozit balpeteği sandviç plağın doğal frekansları ve mod şekilleri üzerinde etkili olduğu görülmektedir.
