Thermal stresses in adhesively bonded double lap joints by FEM

Bu çalışmada, yapıştırıcı ile birleştirilmiş çift bindirme bağlantılarındaki ısıl gerilmeler hesaplanmıştır. Uniform sıcaklık uygulanmasından dolayı oluşan, ısıl gerilme dağılımlarının elde edilmesi için sonlu elemanlar metodu tercih edilmiştir. Isıl gerilme analizleri ANSYS 10.0 programı kullanılarak yapılmıştır. Isıl gerilmeler, birbirinden farklı özelliklere sahip alüminyum ve çelik gibi ince metal levhalar için hesaplanmıştır. Isıl gerilmelerin üzerine farklı ısıl yüklemelerin etkileri incelenmiştir. Elde edilen sonuçlara göre, oluşan ısıl gerilmelerin değerleri ve dağılımları, yapıştırılan malzemelerin özellikleri, sınır şartları ve uniform sıcaklık miktarındaki artıştan önemli ölçüde etkilenmektedir

Yapıştırıcı ile birleştirilmiş çift bindirme bağlantılarında ısıl gerilmeler

In this paper, thermal stresses were calculated in adhesively bonded double lap joints. The finite element method (FEM) was preferred to obtain the thermal stress distributions based on uniform temperature loadings. The thermal stress analyses were carried out using ANSYS 10.0 code. Thermal stresses were computed for the dissimilar sheet materials, i.e. steel and aluminum. The influences of different uniform thermal loadings on thermal stresses were also examined in terms of the FEM results. According to obtained results, the magnitudes and distributions of the improved thermal stresses were significantly affected from bonded material properties, boundary conditions and rising values of uniform thermal loads.
