Yapıştırma bağlantıları endüstride kullanılan geleneksel birleştirme
tekniklerine iyi bir alternatif oluşturmaktadır. Düzgün gerilme dağılımı, sızdırmazlık,
korozyon, farklı türden parçaları birleştirebilme özellikleri ve daha birçok
avantajlarından dolayı yapıştırma bağlantılarına olan ilgi her geçen gün
artmaktadır. Yapıştırma bağlantılarının birçok avantajı olmasına rağmen soyulma
gerilmelerine karşı mukavemetleri iyi değildir. Bu yüzden yapıştırma
bağlantılarında bağlantı modeli büyük önem arz etmektedir. Bu çalışmada, alın
eğrisel bindirme bağlantısı ile düz bindirme bağlantısı olmak üzere iki tip
bağlantı modeli kullanılmıştır. Bu bağlantı modelleri alüminyum alaşımlı
plakalar (A2024-T3) kullanılarak imal edilmiş ve akrilik yapısal yapıştırıcı
(DP810) ile birleştirilmiştir. Eğrisel üst üste binme ve düz üst üste binme
bağlantıları çekme yüküne maruz bırakılmış ve sonuçlar karşılaştırılmıştır.
Sonlu elemanlar analizi için üç boyutlu olarak bağlantı modelleri oluşturulmuş
ve yapıştırma bağlantısının mukavemetini tahmin etmek için enerji prensiplerini
temel alan kohesive bölge modeli kullanılmıştır. Ayrıca nümerik çözümlerin
doğrulanması için doğrulama deneyleri yapılmıştır.
