The Atılım University Department of Civil Engineering was founded in 2000 as a pioneer for the Departments of Civil Engineering among the foundation schools of Ankara. It offers education in English. The Department of Civil Engineering has an academic staff qualified in all areas of the education offered. In addition to a high level of academic learning that benefits from learning opportunities through practice at its seven laboratories, the Department also offers a Cooperative Education program conducted in cooperation with renowned organizations in the construction sector. Accredited by MÜDEK (Association of Evaluation and Accreditation of Engineering Programs) (in 2018), our Department has been granted the longest period of accreditation to ever achieve through the association (six years). The accreditation is recognized by ENAEE (European Network for Accreditation of Engineering Education), and other international accreditation boards.

Abstract

Bu çalışmanın amacı, dönen iki katmanlı kompozit tüplerin elastik analizi için analitik bir yaklaşım sunmaktır. Gerilme ve yer değiştirmelere ait ifadeler elde edilmiş ve kritik akma koşulları von Mises akma kriteri kullanılarak incelenmiştir. Analitik çözümler ayrıca çeşitli malzeme setleri için uygulanmış ve dönme etkisi altındaki gerilme ve yer değiştirme dağılımları bulunmuştur. Akmanın sistemin iç yüzeyinden, iki tüpün etkileşim yüzeyinden veya özel bir durum olarak, iki tüpün iç yüzeylerinden eş zamanlı başlayabileceği bulunmuştur.
The purpose of this study is to present an analytical approach for the elastic analysis of rotating two-layer composite tubes. The expressions of stresses and displacement are obtained and the critical cases of yielding are examined using von Mises yield criterion. The analytical solutions are also checked numerically for material sets and stress and displacement distributions are obtained under rotation. It is found that yielding may begin at the inner surface of the assembly, or at the interface of the two tubes, or as a special case, simultaneously at the inner surfaces of both tubes.
