Abstract
Bu çalışmada, iki eksenli yükleme koşulları altındaki dairesel delikli karbon/epoksi kompozit plakalarda, delik etrafında meydana gelen gerilme dağılımları incelenmiştir. Öncelikle, Filiou ve Soutis [10] tarafından gerilme dağılımı için önerilen yaklaşık çözüm polinomlarının elde edilişi verilmiştir. Daha sonra, sonlu elemanlar yöntemi (FEM) kullanılarak oluşturulan modeller farklı iki eksenli yükleme oranlarıyla (λ) yüklenerek gerilme dağılımları elde edilmiştir. FEM ve analitik yöntemle elde edilen gerilme dağılımları karşılaştırılmış ve açıklamalar yapılmıştır

Abstract
In this study, stress distributions around circular holes in carbon/epoxy composite plates under biaxial loading conditions are investigated. At first, the derivation of the approximate polynomial stress distributions developed by Filiou and Soutis is given [10]. Then, the stress distributions are obtained from the finite element models that are subjected to loading at various biaxiality ratios (λ). The analytical results are compared with the results obtained from FEM and explanations are given
