Abstract

   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.

Keywords

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.

Keywords

Composites coats, buckling load, displacement, finite element methods
