Abstract (2. Language): 
In this study, torsional buckling analysis of a thin-walled tube made of laminated composite materials is carried out. The wall of the tube is of symmetric and cross-ply ( 90 ) 1 2 q +q = o and eight layers. Critical buckling loads are computed by using ANSYS. In the study, the effects of the length of the tube,orientation angle and the dimensions of crosssection on the critical buckling load are examined. The results are given in graphical forms.
Abstract (Original Language): 
Bu çalışmada, kompozit malzemeden yapılmış burulmaya maruz ince cidarlı dikdörtgen kesitli tüplerin burulma burkulması incelenmiştir. Tüplerin cidarları, simetrik çapraz takviyeli ( 90 ) 1 2 q +q = o ve 8 tabakalı olarak kabul edilmiştir. ANSYS paket programı kullanılarak sonlu elemanlar yöntemiyle kritik burulma burkulma yükleri bulunmuştur. Bu çalışmada, tüpün uzunluğu, takviye açısı ve kesit boyutlarının kritik burulma burkulma yükü üzerine etkileri araştırılmıştır. Çalışmanın sonuçları grafikler halinde verilmiştir.
