Bu çalışmada; eliptik delikli ince cidarlı küresel bir elemanın basınç altındaki davranışları Sonlu Elemanlar Analiz (SEA) yöntemi ile parametrik olarak analiz edilmiş ve Yapay Sinir Ağları (YSA) ile modellenmiştir. Modelleme esnasında, küresel elemanın yarıçapı 500 mm. olarak alınmış ve değişken parametrelere göre küresel elemana cidar kalınlığı verilmiştir. Küresel elemanın içinden boydan boya geçen yarıçapları a ve b olan eliptik bir delik tanımlanmıştır. Küresel elemanın iç yüzeyine sabit basınç gerilmesi uygulanmış ve elemanda oluşan gerilmeler ve gerilme yığılma faktörleri optimize edilmiştir. Parametrik modelden elde edilen sonuçlar bir YSA modelinde öğretilerek farklı boyut ve basınç değerleri için eliptik delikli ince cidarlı küresel bir elemanın gerilme, gerinim, deformasyon, gerilme yığılma faktörleri ve farklı teoremlere göre emniyet katsayıları belirlenmiştir.

In this study; The behavior of a thin-walled spherical element with elliptical holes under pressure was analyzed parametrically with the Finite Element Analysis (FEA) method and modeled with Artificial Neural Network (ANN). During modeling, the radius of the spherical element was 500 mm. and the wall thickness of the spherical element is given according to variable parameters. An elliptical hole with radii a and b passing through the spherical element is defined. Constant compressive stress was applied to the inner surface of the spherical element and the stresses and stress concentration factors in the element were optimized. The results obtained from the parametric model were taught in an ANN model and the stress, strain, deformation, stress concentration factors and safety coefficients of a thin-walled spherical element with elliptical holes were determined for different size and pressure values according to different theorems.
