Özet:

 In this study, the effect of the partial edge loadings and changing the orientation angle of the elliptical cutout on the non-dimensional buckling coefficients in rectangular plates with different elliptical cutout sizes have been investigated by the finite element method. In the modeling, the partial loading was applied by 10 increment from 0 up to 100, the orientation angle was changed with a step of 15 from 0 up to 90, the different aspect ratios ab  1 and 2, normalized elliptic cutout short diameter size eb  0.1 and 0.2, and normalized elliptic cutout long diameter size db  0.2, 0.3, 0.4 and 0.5 were selected. From the results obtained, it was determined that the sensitivity of the non-dimensional buckling coefficient of rectangular plates with large elliptical cutouts subjected to different partial loads to the change in the orientation angle was higher than the plates with small elliptic cutouts.

 Bu çalışmada, farklı boyutlardaki eliptik boşluklara sahip dikdörtgen levhalarda, kısmi kenar yüklemelerinin ve eliptik boşluğun yönlenme açısının değiştirilmesinin boyutsuz burkulma katsayıları üzerindeki etkisi sonlu elemanlar yöntemi ile incelenmiştir. Modellemede, kısmi yükleme 0dan 100e kadar 10luk artışlarla uygulanmıştır. Yönlenme açısı 0den 90ye kadar 15lik adımlarla değiştirilmiş, farklı enboy oranları ab  1 ve 2, normalize edilmiş eliptik boşluğun kısa çapı eb  0.1 ve 0.2 ve normalize edilmiş uzun çapı db  0.2, 0.3, 0.4 ve 0.5 seçilmiştir. Elde edilen sonuçlardan, farklı kısmi yüklere maruz bırakılan büyük eliptik boşluklu dikdörtgen levhaların boyutsuz burkulma katsayısının, yönlenme açısındaki değişime karşı hassasiyetinin, küçük eliptik boşluklu levhalara göre daha yüksek olduğu belirlenmiştir.
