KOMPOZİT MALZEMEYLE KAPLI ALÜMİNYUM KİRİŞİN STATİK VE BURKULMA ANALİZİ

Öz

   Bu çalışmada yüzeyi elyaf takviyeli kompozit malzemeyle kaplanmış alüminyum kirişin statik ve burkulma analizi incelenmiştir. Çalışmada Euler-Bernoulli kiriş teorisi kullanılarak problemin çözümü sonlu elemanlar metoduyla gerçekleştirilmiştir. Problemin analizi için MATLAB’ta sonlu elemanlar kodu yazılarak deplasman ve burkulma yükleri hesaplanmıştır. Çalışmada yüzey ve çekirdek tabaka kalınlığının, kompozit malzeme hacim oranının, lif oryantasyon açısının, farklı kiriş konfigürasyonlarının ve farklı boy kalınlık oranlarının deplasman ve burkulma yükleri üzerindeki etkisi incelenmiştir. İncelenen bu parametrelerin kirişin deplasman ve burkulma yüklerini önemli ölçüde etkilediği gözlemlenmiştir.

STATICS AND BUCKLING ANALYSIS OF ALUMINUM BEAMS WITH COMPOSITE COATS

Abstract

   In this study, static and buckling analysis of an aluminum beam coated with fiber reinforced composite material was investigated. Solution of the problem obtained via finite element method by using Euler-Bernoulli beam theory. Finite element simulation code is developed in MATLAB to calculate the displacement and buckling loads. The effect of surface and core layer thickness, composite material volume ratio, fiber orientation angle, different beam configurations and different aspect ratios on displacement and buckling loads was investigated in the study. It has been observed that these parameters have a significant effect on the displacement and buckling loads of the beam.
