Yapıştırıcı ile birleştirilmiş bağlantıların kullanımı otomotiv ve havacılık sektörlerinde oldukça yaygındır. Korozyona dayanıklılığı, titreşim absorbe yeteneği ve düşük kütleye sahip olması yapıştırıcıların bağlantılarda sıkça tercih edilmelerinin başlıca nedenleri olarak sıralanabilir. Bu çalışmada, yapıştırılarak bağlanan bindirme bağlantılar üzerinde dört noktalı eğme testi deneysel ve sayısal olarak incelenmiştir. Deneysel çalışmada bindirme uzunluğu ve yapışkan kalınlığı sabit 5 farklı geometrideki numunelere 9 faklı konumda bükme yüklemesi uygulanmıştır. Deneysel çalışmadan kullanılan numunelerin sonlu eleman modelleri ANSYS yazılımında aynı yükleme şartlarında analiz edilmiş ve soyulma ve kesme gerilmeleri bindirme uzunluğu boyunca elde edilmiş ve deneysel sonuçlar sonlu elemanlar sonuçları ile doğrulanmıştır. Mevcut çalışma gösteriyor ki yapıştırıcı ile birleştirilmiş bağlantılarda bükme yükünün konumu test sonuçlarına belli oradan etki etmektedir.

The use of adhesive bonded joints is very common in the automotive and aerospace industries. Corrosion resistance, vibration absorbing ability and low mass can be listed as the main reasons why adhesives are frequently preferred in connections. In this study, the four-point bending test on glued lap joints was investigated experimentally and numerically. In the experimental study, bending loading was applied to the specimens in 5 different geometries with fixed overlap length and adhesive thickness at 9 different positions. The finite element models of the samples used in the experimental study were analyzed in the ANSYS software under the same loading conditions and the peeling and shear stresses were obtained along the overlap length and the experimental results were verified with the finite element results. The present study shows that the position of the bending load in adhesively bonded joints has a certain effect on test results.
