In this study, the critical buckling load of hybrid composite plates with three layers was analyzed using numerical and statistical methods. Laminated hybrid composite plates were designed using glass-epoxy, boron-epoxy, carbon-epoxy, and metal. The outermost layers of the plates were modelled using fiber reinforced composite materials whereas the innermost layer of plates was created using Aluminum material (Al2024-T3). Numerical buckling behavior was calculated using finite element software ANSYS. Analysis of signal-to-noise ratio was utilized to decide the effects and optimal levels of the plates and their fiber orientation angles on buckling load. Analysis of variance at the 95 % confidence level was employed to indicate the control factors which have significant effect on the buckling responses.

Öz

Bu çalışmada üç tabakalı hibrit kompozit plakaların kritik burkulma yükü sayısal ve istatiksel metotlar kullanılarak analiz edilmiştir. Tabakalı hibrit kompozit plakalar cam/epoksi, bor/epoksi, karbon/epoksi ve metal kullanılarak dizayn edilmiştir. Plakaların en üst tabakaları fiberle güçlendirilmiş kompozitlerden modellenirken en iç tabakaları Alüminyum (Al2024-T3) malzemeden oluşturulmuştur. Sayısal burkulma davranışı sonlu elemanlar yazılımı ANSYS kullanılarak hesaplanmıştır. Sinyal-Gürültü oran analizi burkulma davranışı üzerinde plakaların optimal seviyelerini ve fiber oryantasyon açılarının etkilerini karar vermek için kullanıldı. Burkulma yanıtları üzerinde önemli etkiye sahip olan kontrol faktörlerini belirlemek için % 95 güven seviyesinde varyans analizi uygulandı.
