Abstract

In this study, the post-buckling behavior of shells is investigated using 9-noded isoparametric shell
elements. 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

Toplam Lagrange Yöntemi ile Kabukların Burkulma Ötesi Analizi

Abstract

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

Keywords

Kabuk eleman, burkulma ötesi davranış
