heal.abstract	Cracking damage in a stiffened panel is likely to have a deleterious effect on its ultimate strength and collapse characteristics. The present study examines this problem for a crack with different configurations and increasing length inserted in a stiffened plate. The cracks are positioned normal to the direction of the prescribed axial compression and crack propagation is not considered. A key feature of this work is the role of crack closure on the structural response. The ultimate strength reduction and collapse response are reported for stiffened plates of varying aspect ratio. Finally, an FE modeling approach is presented, which has the potential to extend this investigation to multi-bay panels at a reasonable computational cost. © 2011 Elsevier Ltd.
