Thermal buckling analysis of laminated plates with variable angle fiber orientation
Öz: The thermal buckling response of square plates with variable angle tows under simply supported conditions is modeled numerically. The path of variable angle tow is modeled as a function of lateral location. The classical lamination theory utilizes fiber paths to calculate thermal loads and stiffness matrices. Using Kirchhoff plate theory and finite element theory, the global material stiffness matrix and the global geometric stiffness matrix of the plate under thermal buckling loads are obtained. By using these matrices, eigenvalues or critical buckling temperature is obtained and the buckling response of the plate is examined. The theoretical results are validated by studies in the literature and finite element models. It has been seen even in an unoptimized span of a sample composite material, variable angle tows (VATs) were 8,60% more resistant to thermal buckling than common composite layups.
Anahtar Kelime: Değişken fiber açılı kompozit plakların termal burkulma analizi
Öz: Bu çalışmada, değişken açılı fiberlere sahip kare kompozit plakaların basit mesnet koşulu altında termal burkulma analizini yapmak için bir kod geliştirilmiştir. Değişken açılı fiberlerin oryantasyonu, yatay konumun bir fonksiyonu olarak modellenmiştir. Klasik laminasyon teorisi, termal yükleri ve direngenlik matrislerini hesaplamak için fiber yollarını kullanır. Khirchoff plaka teorisi ve sonlu elemanlar teorisinin modelleme yöntemleri kullanılarak, termal burkulma altındaki plakanın global malzeme rijitlik matrisi ve global geometrik rijitlik matrisi elde edilmiştir. Bu matrislere gerekli işlemler uygulanarak bu analiz için özdeğerler, yani kritik burkulma sıcaklığı elde edilebilir ve plakanın durumu yorumlanabilir. Sayısal çalışmadan elde edilen sonuçlar, literatürdeki çalışmalar ve sonlu eleman modelleri ile doğrulanmıştır. Örnek bir kompozit malzemenin optimize edilmemiş bir aralığında bile, değişken açılı kompozitlerin düz serimli kompozitlere göre termal burkulmaya karşı %8,60 daha dirençli olduğu görülmüştür.
