4. The cellular structure of claim 1 , wherein:
each of the twelve sides of the twelve-cornered cross section is substantially straight; and
cross-sectional thicknesses of the twelve sides of the twelve-cornered cross section are each a substantially same thickness.

5. The cellular structure of claim 1 , wherein each cell of the plurality of cells further comprises a plurality of walls, each wall of the plurality of walls having a length that extends between longitudinal edges of the respective wall, wherein intersections of the longitudinal edges of the plurality of walls define twelve corners of the twelve-cornered cross section.

6. The cellular structure of claim 1 , wherein the cellular structure is made from a material selected from the group consisting of steel alloys, titanium alloys, aluminum alloys, magnesium alloys, nylons, polymers, plastics, composites, fiber-reinforced composites, silicone, semiconductor, papers, rubber, foams, gels, woods, corks, shape-memory materials, and combinations thereof.

7. The cellular structure of claim 1 , wherein the cellular structure is formed by stamping, bending, press forming, hydro-forming, molding, casting, extrusion, roll forming, machining, forging, 3D printing, or a combination thereof.

8. The cellular structure of claim 1 , wherein one or more cells are at least partially filled with a foam material.

9. The cellular structure of claim 1 , wherein the cellular structure is positioned within a structural component to enhance at least one of strength, energy absorption, stability of axial crush, and an axial crush distance of the structural component.

10. The cellular structure of claim 1 , wherein each cell of the plurality of cells shares at least one wall with another cell of the plurality of cells.
