Abstract

In this study, comparisons of 3-D numerical simulations of stringer/ring/ orthogonally stiffened laminated cylindrical shells are presented using two different finite element codes. The three dimensional simulation models were developed by previously developed finite element code COMPAN and commercial FE code ANSYS in the consideration of the comparison of results.

Özet

Bu çalışmada yanal/halka/ortotropik berkitmeli, katlı kompozit dairesel kesitli silindirlerin üç boyutlu sayısal benzetimleri, iki farklı sonlu elemanlar analiz kodu ile elde edilerek sunulmaktadır. Üç boyutlu olarak oluşturulan modellemeler, COMPAN sonlu elemanlar kodu ve ticari yazılım ANSYS ile oluşturularak sonuçlar karşılaştırılmıştır. Yanal/halka/ortogonal berkitmeli dairesel kesitli silindirler, değişik üç boyutlu eleman çeşitleri kullanılarak oluşturulmuşlardır. Katlı kompozit silindirik kabukların davranışları, iç basınç yüklemeleri altında yerdeğişme, gerilme ve genleme dağılımlarından yararlanılarak incelenmiş, modelleme farklılıklarından doğan sonuçlar karşılaştırılarak tartışılmıştır. Berkitmesiz ana gövde ile değişik berkitmelere sahip kompozit silindirlerde, bu iki farklı bölgenin kesiştiği topuk olarak adlandırılan bölgelerde oluşan gerilme ve genleme yığılmaları ortalama maksimum değerler verilerek tespit edilmiştir.
