Özet
Bu çalısmada, karma bağlantı uygulanmıs farklı metal plakalarda meydana gelen gerilmeler incelenmistir. Karma bağlantı, pim bağlantısı ve yapıstırıcı bağlantısından meydana getirilmistir. Bağlantısı yapılan alt levha alüminyum olarak sabit tutulurken, üst levha sırasıyla çelik, bakır, titanyum ve alüminyum olarak modellenmistir. Yapıstırıcı olarak epoksi kullanılmıstır. Çözümde, üç boyutlu modeller olusturularak, sonlu elemanlar metodu kullanılmıstır. Daha önceki birçok çalısmada, sadece yapıstırıcı bağlantıları veya pim bağlantıları incelenmis olmakla birlikte, bu çalısmada her iki bağlantının birlikte kullanıldığı karma bir bağlantı analiz edilmistir. Karma bağlantıya, çekme yükü ve 40 oC uniform sıcaklık yükleri birlikte uygulanmıstır. Alüminyum-alüminyum karma bağlantılarda meydana gelen gerilmeler en düsük değerlerde meydana gelirken, en yüksek gerilmelerin alüminyum-çelik karma bağlantılarda meydana geldiği görülmüstür. Bir baska ifadeyle, aynı malzemeden yapılan benzer plakalardan meydana gelen karma bağlantılar, daha düsük gerilmelere neden olmustur.
In this study, the stresses occurred on metal plates which is applied hybrid joints were investigated. Hybrid joint was designed from both pinned joint and adhesively bonded joint. The joined lower adherent material was selected as aluminum constantly, whereas joined upper adherent materials were modeled as steel, copper, titanium and aluminum. The epoxy was used as adhesive. In solution, the finite element method (FEM) was used via creating three dimensional models. In many previous studies, adhesive joints or pinned joints were only investigated, but in this study a hybrid joint based on both pinned joint and adhesively bonded joint were analyzed. Tensile load and uniform temperature loading as 40 oC were applied with together on hybrid joint. The higher stresses were observed on aluminum-steel hybrid joint, while the lower values of stresses were obtained aluminum-aluminum hybrid joint. In other words, similar sheets made same material caused the lower stresses on the hybrid joint.
