An axisymmetric linearly elastic and isotropic finite
cylinder with rigid ends and a circumferential edge crack subjected to axial
tension is considered. Finite cylinder problem is obtained from an infinite
cylinder containing an internal ring-shaped crack and two penny-shaped rigid
inclusions. Navier equations are solved by
using Fourier and Hankel transforms. Formulation is reduced to three singular
integral equations which are converted to a system of linear algebraic
equations with the aid of Gauss-Lobatto and Gauss-Jacobi integration formulas.
Stress intensity factors at the edges of crack and around the corner of the
cylinder are calculated.

doğrusal elastik ve izotropik malzemeden imal edilmiş, çevresel bir kenar
çatlağı içeren rijit uçlu sonlu uzunlukta eksenel simetrik bir silindir
incelenmiştir. Sonlu silindir problemine ulaşmak için, halka şeklinde iç çatlak
ve iki dairesel şekilli enklüzyon içeren sonsuz bir silindirden yola çıkılmıştır.
Navier denklemleri Fourier ve Hankel dönüşümleri kullanılarak çözülmüştür.
Formülasyon tekil integral denklemlerine indirgenmiş ve Gauss-Lobatto ve
Gauss-Jakobi integrasyon formülleri ile doğrusal cebrik denklem takımlarına
dönüştürülmüştür. Çatlağın kenarlarındaki ve silindirin çevresi etrafındaki
gerilme yığılma faktörleri hesaplanmıştır.
