Sandviç Kompozit ve Metal Plakalar ile Oluşturulan Tek Bindirmeli Yapıştırma Bağlantılarının Mekanik Özelliklerinin Deneysel ve Nümerik Yaklaşım ile Belirlenmesi

Bu çalışmada, farklı malzemeler kullanılarak oluşturulan tek bindirmeli yapıştırma bağlantılarının mekanik özellikleri deneysel ve nümerik yaklaşım ile belirlenmiştir. Tek bindirmeli yapıştırma bağlantılarında plaka malzemesi olarak çelik, alüminyum ve alüminyum sandviç kompozit malzeme, yapıştırıcı olarak ise Araldite 2015 epoksi yapıştırıcı kullanılmıştır. Aynı malzemeye sahip plakalar kullanılarak elde edilen yapıştırma bağlantılarının yanı sıra, farklı malzemelere sahip plakalardan oluşan yapıştırma bağlantıları da bu çalışma kapsamında incelenmiştir. Deneysel yaklaşımda çekme testleri 1 mm/dak çekme hızında gerçekleştirilmiştir. Deneysel yaklaşım sonunda her bir yapıştırma bağlantısının gerilme-birim şekil değiştirme grafikleri belirlenmiştir. Ayrıca, plaka malzemesi olarak kullanılan alüminyum sandviç kompozit malzeme de yer alan polietilen polimerinin XRD testi ile karakterizasyonu yapılmıştır. Nümerik yaklaşımda, deneysel yaklaşımda kullanılan tek bindirmeli yapıştırma bağlantı geometrisi Ansys sonlu elamanlar programında oluşturulmuştur. Model oluşturulurken yapıştırıcı ile plakalar arasında non-lineer kontak kurulmuş ve deney şartlarını karşılayan sınır şartları uygulanmıştır. Bindirme bağlantılarının non-lineer modellenmesi, doğru sınır koşullarının uygulanması ve doğru temas tipinin seçilmesi nedeniyle nümerik sonuçların deneysel sonuçlarla benzer bir eğilim gösterdiği görülmüştür.

Determination of Mechanical Properties of Single Lap Joints Having Sandwich Composite and Metal Adherend by Experimental and Numerical Approach

In this study, the mechanical properties of single lap joints having different adherends were determined by experimental and numerical approaches. Steel, aluminum, and aluminum sandwich composite material were used as adherend, and Araldite 2015 epoxy adhesive was used as adhesive in single lap joints. Alongside the single lap joints obtained by using similar adherends, different adherends were also examined within the scope of this study. In the experimental approach, tensile tests were carried out at a rate of 1 mm/min. At the end of the experimental approach, the stress-strain plots of each single lap joint were determined. In addition, the characterization of the polyethylene polymer, which is also included in the aluminum sandwich composite material used as the adherend , was made in experimental approach by XRD test. In the numerical approach, the single lap joint geometry used in the experimental approach was created in the Ansys finite element program. A non-linear contact was established between the adhesive and the adherend, and boundary conditions were applied that meet the experimental conditions. It was observed that the numerical results show a similar tendency with the experimental results due to the non-linear modeling of the lap joints, the application of the correct boundary conditions, and the selection of the correct contact type.
