Young’s modulus estimation techniques for the randomly oriented natural fiber reinforced composites: Finite element analysis and analytical models

Öz:
In the study, elastic modulus estimation methods of natural fiberreinforced composites considered as alternatives to synthetic fiberreinforced composites have been investigated. Finite element analysis(FEA) and some mathematical models which are used for synthetic fiberreinforced composites were preferred. During the study, randomlyoriented cotton fiber reinforced composites at different fiber ratio byvolume were investigated and the tensile test results were foundexperimentally. Experimental data were compared with data obtainedusing finite element method and current analytical models. Particularlyin low fiber reinforced composite samples, the data obtained from theanalytical models approximated between 2-4% of the experimentaldata. On the other hand, in the analysis by the finite element method, itis observed that the difference with the experimental results is openedas the high deformations are occurred. The most suitable analyticalmodels have been found in the study and have been proposed for suchcomposites. Moreover, the behavior of composites can be simulated byfinite element methods and closed results (17-23%) are revealed in thisrespect.

Gelişigüzel doğal lif takviyeli kompozitlerin elastiklik modülü tahmin yöntemleri: Sonlu elemanlar analizi ve analitik modeller

Öz:
Çalışmada sentetik lif takviyeli kompozitlere alternatif olarak düşünülen doğal lif takviyeli kompozitlerin elastisite modülü tahmin yöntemleri incelenmiştir. Yöntem olarak sonlu elemanlar analizi ve sentetik lif takviyeli kompozitler için kullanılan matematiksel modellerin uygunlukları araştırılmıştır. Çalışma boyunca ele alınan kompozitlerhacimce farklı oranlarda gelişigüzel pamuk lifi takviyeli olup çekme test sonuçları deneysel olarak bulunmuştur. Deneysel veriler sonlu elemanlar yöntemi ve mevcut analitik modeller kullanılarak elde edilen veriler ile kıyaslanmıştır. Özellikle düşük lif takviyeli kompozit numunelerde analitik modellerden elde edilen veriler deneysel verilere yaklaşık olarak %2-4 arasında yaklaşmıştır. Diğer yandan sonlu elemanlar yöntemiyle yapılan analizlerde ise yüksek şekil değiştirme oranlarına doğru gidildikçe deneysel sonuçlarla aradaki farkın açıldığı gözlenmiştir. Çalışma neticesinde en uygunan alitik modeller bulunmuş ve bu tarz kompozitler için önerilmiştir. Ayrıca sonlu elemanlar yöntemiyle kompozitlerin davranışları taklit edilebilmiş ve deneysel değerler ile yakın (%17-23) sonuçlar ortaya çıkarılmıştır.
