    Abstract: The subject of the disclosed embodiments is a method of optimizing stiffened panels under stress. In particular, the method makes it possible to determine the stress distribution in stiffened panels with postbuckling taken into account. The method proposed is a coupling between an overall, linear stress calculation approach, based on strength-of-materials results, and a local, nonlinear approach for the behavior of the stiffened panel. The disclosed embodiments fall within the field of aeronautical design, at the pilot study stage in the definition of a civil transport airplane of conventional architecture.

    Abstract: The invention relates to a process for making a reinforced curved metallic structure, made from a heavy-gauge or plate-gauge sheet of an aluminium alloy containing scandium.The process consists in combining forming (200) and machining (300) steps, the forming step (200) giving the structure curvature(s) and the machining step (300) producing a network of ribs for reinforcing the structure. A finishing step (400) can complete the preceding steps.Such a process makes it possible to obtain a monobloc metallic structure with good mechanical properties simply and quickly. Application to the manufacture of a reinforced curved metallic structure of an aircraft subassembly.
