Abstract

In this study, the influence of pressure stiffness on the torsional buckling of thin and
moderately thick laminated composite perfect cylinders under external hydrostatic pressure is
investigated. A degenerated-curved shell element is used to obtain the numerical results. First, a
verification problem is solved and the element is validated for stability analysis including pressure
stiffness. Then, cross-ply and angle-ply laminated composite cylinders are examined for selected lengthradius
ratios and stacking sequences. The results obtained show that, pressure stiffness may have a
stabilizing effect against torsional buckling especially for thick orthotropic cylinders.

BASINÇ RİJİTLİĞİNİN HİDROSTATİK BASINÇ ETKİSİ ALTINDAKİ KATMANLI KOMPOZİT SİLİNDİRLERİN BURULMALI BURKULMALARINA ETKİSİ

Abstract

Bu çalışmada hidrostatik basınç altındaki ince ve orta kalınlıkta katmanlı kompozit kusursuz
silindirlerin burkulmasında basınç rijitliğinin etkisi araştırılmıştır. Sayısal neticeler dejenere-eğri bir
kabuk elemanı kullanılarak elde edilmiştir. Öncelikle bir doğrulama problem çözülmüş ve eleman
basınç rijitliğini içeren stabilite tahkiki için doğrulanmıştır. Daha sonra, dik-açılı ve eğik-açılı katmanlı
kompozit silindirler seçilen uzunluk/çap değerleri ve katman düzenleri için incelenmiştir. Elde edilen
neticeler basınç rijitliğinin özellikle kalın otrotropik silindirlerde burulmalı burkulmayı engellediğini
göstermektedir.
