SHAPED METAL PANELS AND FORMING SAME BY SHOT PEENING

摘要

A panel, such as is intended for an aircraft wing panel, has continuous ri bs extending on one surface. The panel is formed, or given a dihedral bend, by shot peening the ribs at a V-shaped section to expand the V-shaped sections and thus deform the panel. A strong formed panel is thus provided with continuous rib s. Further shot peening steps can be carried out on the panel for further shaping.
