HİBRİD TİP BAĞLANTI UYGULANMIŞ TERMOPLASTİK KOMPOZİT PLAKALARDAKİ ISIL KAYMA GERİLMELERİNİN BELİRLENMESİ

Bu çalışmanın amacı hibrid tip bağlantı uygulanmış termoplastik kompozit plakalardaki ısıl kayma gerilmelerinin belirlenmesidir. Hibrid bağlantı yapıştırıcı ve iki paralel pim uygulaması şeklinde tasarlanmıştır. Problemin çizimi ve çözümü ANSYS yazılımı kullanılarak gerçekleştirilmiştir. Bu yüzden çözümlerde sonlu elemanlar metodu kullanılmıştır. Hibrid bağlantının modellenmesi üç boyutlu olarak yapılmıştır. Tasarlanan yapıdaki ısıl gerilmeler uygulanan uniform sıcaklık yükleri nedeniyle meydana gelmiştir. Elde edilen sonuçlar, ısıl gerilmelerin uniform sıcaklık artışına çok önemli oranda bağlı olduğunu göstermiştir. Kısaca, ısıl kayma gerilmeleri, sıcaklık yükündeki artışa bağlı olarak artmıştır

DETERMINATION OF THERMAL SHEAR STRESSES ON TERMOPLASTIC COMPOSITE ADHERENTS JOINED HYBRID TYPE

This paper aims to determine of thermal shear stresses on thermoplastic adherents which are joined by hybrid type. It is designed both adhesive and two parallel pins. Both plotting and solving of this problem were done using ANSYS software. Therefore solutions were performed with finite element methods (FEM). Modeling of hybrid joint was established as three dimensional. Thermal stresses were caused to apply uniform thermal loads on designed structure. Determined results pointed out that thermal shear stresses were strictly affected of increasing uniform thermal loads. Briefly, their values were increased by increasing of thermal loadings.
