Toplam Lagrange Yöntemi ile Kabukların Burkulma Ötesi Analizi

Bu çalışmada, 9-düğümlü izoparametrik kabuk eleman kullanılarak kabukların burkulma ötesi davranışıincelenmektedir. Formülasyonda toplam Lagrange yaklaşımı esas alınmakta ve malzeme lineer elastik kabuledilmektedir. Lineer olmayan denge denklemleri yay-boyu metodu (arc-length method) ile çözülmektedir. Değişiknümerik örnekler çözülerek kabukların burkulma ötesi davranışı elde edilmiştir

Anahtar Kelimeler:

Kabuk eleman, burkulma ötesi davranış

Post Buckling Behavior of Shells Using Total Lagrangian Method

In this study, the post-buckling behavior of shells is investigated using 9-noded isoparametric shellelements. Total Lagrangian approach is used in the formulation and shell material is assumed to be linearly elastic.Non-linear equilibrium equations are solved by arc-length method. Various examples were analyzed to obtain postbuckling behavior of shells

Keywords:

Shell element, post-buckling behavior,
