Abstract: The invention relates to a structured material web, particularly a metal web, having a multi-dimensional structure comprising beads or creases and structures disposed next to each other and each formed by a surface section enclosed by the beads or the creases, wherein each of the structures has a dedicated location with a hole, and the surface section in every other location of the structure is formed by an incline toward the dedicated location.
Abstract: According to the invention thin sheets of foil are stiffened in a particular way by means of vault-structuring. The vault-structuring occurs either by self-organizing or following a self-organized design with a spade-shaped or drop-shaped pattern.
