Abstract (2. Language): 
In this study, the problem of a ring shaped-crack contained in an infinitely long solid cylinder of elastic perfectly-plastic material is considered. The problem is formulated for a transversely isotropic material by using integral transform technique under uniform load. Due to the geometry of the configuration, Hankel and Fourier integral transform techniques are chosen and the problem is reduced to a singular integral equation. This integral equation is solved numerically by using Gaussian Quadrature Formulae and the values are evaluated for discrete points. The plastic zone lengths are obtained by using the plastic strip model.

Bu çalışmada yüzük şeklinde çatlak bulunduran elastik-ideal plastik sonsuz uzunluklu bir silindir ele alınmıştır. Problem düzgün yayılı yük etkisi altında enine izotrop bir malzeme için integral dönüşüm tekniği kullanılarak formüle edilmiştir. Problemin geometrisi gereğince Hankel ve Fourier integral dönüşüm teknikleri seçilmiş ve problem bir tekil integral denklemine indirgenmiştir. Bu integral denkleminin belli noktalardaki değerleri Gauss Quadrature formülü kullanılarak sayısal olarak elde edilmiştir. Plastik bölge uzunlukları, plastik bant modeli kullanılarak elde edilmiştir.
