An infinite cylinder, of isotropic and linearly
elastic material, with an internal ring shaped crack and two penny shaped rigid
inclusions was considered in this study. The considered cylinder was subjected
to axial tensile forces from its two ends. The complex problem of the axially
loaded infinite cylinder was solved by using the superposition of two problems
including: (i) an infinite cylinder, without any cracks or inclusions, loaded
at infinity and (ii) an infinite cylinder with an internal ring shaped crack
and two penny shaped inclusions and free of loading. Associated Navier
equations are solved with Fourier and Hankel transforms to obtain general expressions
for the considered problem. Then, the considered problem is reduced to three
singular integral equations and numerically solved by using Gauss-Lobatto
integration formula with associated system of linear algebraic equations.

Bu çalışmada elastik
ve izotropik malzemeden imal edilmiş, halka şeklinde bir iç çatlak ve daire
şeklinde iki adet rijit enklüzyon içeren sonsuz bir silindir incelenmiştir.
İncelenen silidir iki ucundan eksenel yüke tabi tutulmuştur. Eksenel yüklenmiş
sonsuz silindiri içeren karmaşık problem iki problemin süperpoze edilmesiyle
çözülmüştür. Bu problemler: (i) çatlak veya enklüzyon içermeyen sonsuzda
yüklenmiş bir sonsuz silindir, (ii) yükleme
altında olmayan, halka şeklinde bir iç çatlak ve iki daire şekilli enklüzyon
içeren sonsuz silindirdir. İlgili Navier eşitlikleri, Hankel ve Fourier
dönüşümleri kullanılarak çözülerek, ilgilenilen probleme yönelik genel ifadeler
elde edilmiştir. Sonra, problem üç adet tekil integral denklemine indirgenmiş
ve ilgili doğrusal cebrik denklem takımı Gauss- Lobatto integrasyon formülleri
kullanılarak sayısal yöntemlerle çözülmüştür.
