Abstract

Bu çalışma, ince eğri elyaflı kompozit plaka çerçeve yapıların dinamik ve burkulma analizlerini Klasik Plaka Teorisi ve Sonlu Elemanlar Analizi ile incelemektedir. Bu amaçla, yapının eğrilik yarıçapının, en-boy oranının ve elyaf düzeninin ilk on doğal frekans, mod şekilleri, kritik burkulma yükü ve birinci dinamik kararlılık bölgeleri üzerine olan etkileri araştırılmıştır. Ayrıca, iki bölütlü yapı da ele alınmıştır. Dinamik ve burkulma analizleri MATLAB üzerinden bir bilgisayar kodu aracılığı ile gerçekleştirilmiştir. Buradan elde edilen sonuçlar aynı analizlerin ANSYS üzerinden gerçekleştirilmesi ile doğrulanmıştır. Sonuçlar olarak yapının en-boy oranının ve laminasyon düzeninin dinamik özellikleri büyük ölçüde etkilediği, eğrilik yarıçapının ise diğer parametrelere göre yapının dinamik özellikleri üzerinde daha az etki oluşturduğu görülmüştür.

Dynamic and Buckling Analysis of the Laminated Composite Curved Plate Frame Structures

Abstract

This study presents the dynamic and buckling analysis of the laminated composite thin arch plate frame
structures employing Classical Plate Theory with Finite Element Analysis. For this purpose, The effects of the radius of curvature, aspect ratio, and stacking order of such structures on the first ten natural frequencies, mode shapes, critical buckling load, and the first unstable regions are investigated. Besides, the two-bay curved plate frame structure is investigated. In order to perform dynamic and buckling analyses, a computer code is developed and executed via MATLAB. The results are compared and validated with those of ANSYS. It is concluded that the aspect ratio or the stacking order affects the dynamic characteristics of the curved plate frame structure considerably while the radius of curvature relatively has less impact on such dynamic properties of the structure.
