Abstract :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 (a/b = 1 and 2), normalized elliptic cutout short diameter size (e/b = 0.1 and 0.2), and normalized elliptic cutout long diameter size (d/b = 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.
