In this paper, a combination of the series method and the perturbation theory has been proposed to calculate the elastic buckling stresses of panels with two edges simply supported subjected to the uniform axial stress by considering the linear theory of Donnell as the governing equation. As a parametric study, the effects of changing the radius, length, and sector angles of the panels on the buckling stresses have been investigated and the results have been compared with the finite elements method. Also, to find the buckling stress, a correction factor for the Lorenz formula has been proposed.
