Abstract
The integrally stiffened panel includes one or more stiffeners oriented in one direction, and one or more stiffeners oriented in a different direction. The stiffeners are integral with a sheet member and intersect at a joint. The joint is configured to incorporate a pocket at the stiffener intersections. The pocket geometry is inverse to the stiffener geometry, and thereby provides moment and stiffness continuity across the joint and between adjacent intersecting stiffeners.
