Abstract

In this study, critical buckling load analysis for first mode of layered functionally graded shell structures made of silicon nitride (Si3N4)/stainless steel (SUS304) systems is studied. The shell structures are considered as three layers and the layer positions are carried out according to L9 (33) orthogonal array. The mechanical properties of the layers are calculated according to a simple rule of mixture of composite materials. The mechanical properties of the layers is assumed to be control factors. Optimum layer levels are obtained using signal to noise (S/N) analysis. Significant layers and their percent contributions on the results are detected using analysis of variance (ANOVA). Maximum buckling load value is carried out based on different arrangements of optimum layer levels.

Özet

Bu çalışmada, silisyum nitrür (Si3N4)/paslanmaz çelik (SUS304) sistemlerinden yapılmış tabakalı fonksiyonel derecelendirilmiş kabuk yapıların birinci mod için kritik burkulma yük analizi çalışılmıştır. Kabuk yapılar üç tabakalı olarak düşünülmüş ve tabaka pozisyonları L9 (33) ortogonal diziye göre gerçekleştirilmiştir. Tabakaların mekanik özellikleri, kompozit malzeme karışımının basit kuralına bağlı olarak hesaplanmıştır. Tabakaların mekanik özellikleri kontrol faktörleri olarak kabul edilmiştir. Optimum tabaka seviyeleri sinyal gürültü (S/N) analizi kullanılarak elde edilmiştir. Sonuçlar üzerinde önemli tabakalar ve onların yüzde katkıları varyans analizi (ANOVA) kullanılarak tespit edilmiştir. Maksimum burkulma yük değeri optimum tabakaların farklı sıralamasına bağlı gerçekleştirilmiştir.
