Abstract
Buckling under compression is a common phenomenon for thin-walled structures. Under certain conditions, they can also buckle locally under tensile loads. In this paper, the buckling of cracked panels is investigated. Effects of some parameters such as the length and orientation of crack, length, width and thickness of the panel and boundary conditions on the compressive and tensile buckling loads are determined. The results show that the dimensions of panels have the least and characteristics of crack have the most effect on the buckling.
