Abstract

In this study, the effects of variations of subtended angle, curvature of a laminated curved beam and orientation angle, having an in-plane curvature, on the natural frequencies and buckling load have been investigated by using the Finite Element Method. Sabir and Ashwell’s displacement functions have been used to develop a finite element model to employ in this study. The results obtained with the present element are compared with the results obtained from ANSYS program.

Özet

Bu çalışmada, düzlem içerisinde belirli bir eğriliğe sahip tabakalı kompozit dairesel bir yay parçasının merkez açısının, eğrilik yarıçapının değişiminin ve tabakalardaki fiber açılarının doğal frekans ve burkulma yüküne etkileri sonlu elemanlar metodu kullanılarak araştırılmıştır. Bu analizde kullanılan sonlu eleman modelinin oluşturulması için Sabir ve Ashwell’in yer değiştirme fonksiyonları kullanılmıştır. Geliştirilen modelle elde edilen sonuçlar ANSYS programından elde edilen sonuçlarla karşılaştırılmıştır.
