    摘要: Beaded panels and method of forming beaded panels. A beaded panel as described herein includes a base structure comprising a sheet of material, and beads that comprise a protrusion on a first side of the base structure, and a concavity on an opposing second side of the base structure. A geometry of the beads comprises a center section having a conic shape about a longitudinal axis, flared sections symmetric about the center section along the longitudinal axis, and a transition section that curves outward from a base of the center section and the flared sections to blend with a flat surface on the first side of the base structure.

    摘要: A wall having a stiffener integrally formed therein is provided. The stiffener includes a first side panel that extends from the wall, a second side panel that extends from the wall, and an intermediate panel that extends between the first side panel and the second side panel. The first and second side panels and the intermediate panel at least substantially enclose a cavity there between. A method for integrally forming the stiffener in the wall includes the steps of: (a) providing the wall; (b) forming the wall to provide the first and second side panels and the intermediate panel of the stiffener; and (c) bending at least one of the first and second side panels and the intermediate panel of the stiffener so that they at least substantially enclose a cavity there between.
