A strengthening member for a vehicle, a vehicle including a strengthening member, and a method of making a strengthening member for a vehicle is provided. The strengthening member can have a twelve-cornered cross section that includes sides and corners. The sides can include eight straight sides and four curved sides. A length of each straight side can be substantially the same, a radius of a curvature of each curved side can be substantially the same, and a ratio of the straight side length to the curvature radius may range from about 0.9 to about 1.6. In a motor vehicle, length of each straight side of the cross section of the strengthening member can range from about 10 mm to about 200 mm and the radius of the curvature of each curved side of the cross section of the strengthening member can range from about 3 mm to about 400 mm.

1. A strengthening member for a vehicle, the strengthening member comprising a twelve-cornered cross section including sides and corners, the sides comprising eight straight sides and four curved sides, wherein a length of each straight side is the substantially the same, a radius of a curvature of each curved side is substantially the same, and a ratio of the straight side length to the curvature radius ranges from about 0.9 to about 1.6. 2. The strengthening member of claim 1, wherein the ratio of the straight side length to the curvature radius ranges from about 1.30 to about 1.35. 3. The strengthening member of claim 1, wherein the ratio of the straight side length to the curvature radius is about 1.33. 4. The strengthening member of claim 1, wherein the curved sides are semi-circular. 5. The strengthening member of claim 1, wherein the curved sides are semi-elliptical. 6. The strengthening member of claim 1, wherein the sides and corners create twelve internal angles, wherein each internal angle is about 90 degrees. 7. The strengthening member of claim 1, wherein an outer dimension of the cross section is substantially square-shaped. 8. The strengthening member of claim 1, wherein an aspect ratio of the cross section is about 1.0. 9. The strengthening member of claim 1, wherein the radius of the curvature ranges from about 3 mm to about 400 mm. 10. The strengthening member of claim 1, wherein at least one side tapers along a longitudinal length of the strengthening member. 11. A method for manufacturing a strengthening member for an automotive vehicle, the strengthening member comprising a twelve-cornered cross section including eight straight sides and four curved sides, wherein a length of each straight side is the same, a radius of a curvature of each curved side is the same, the method comprising: fabricating one or more sections of the strengthening member; andtuning the ratio of the straight side length to the curvature radius to be about 0.9 to about 1.6. 12. The method of claim 11, further comprising tuning the ratio of the straight side length to the curvature radius to be about 1.3 to about 1.6. 13. The method of claim 11, tuning the ratio of the straight side length to the curvature radius to be about 1.30 to about 1.35. 14. The method of claim 11, wherein fabricating the one or more sections comprises stamping, pressing, hyrdroforming, molding, casting, forging, roll forming, and/or extruding each of the one or more sections. 15. The method of claim 11, further comprising fabricating the one or more sections from steel alloys, titanium alloys, aluminum alloys, magnesium alloys, nylons, plastics, polymers, composites, fiber-reinforced composites, shape memory materials, or a combination thereof. 16. The method of claim 11, further comprising joining the one or more sections by one or more of welding, brazing, soldering, press fitting, adhesion, and fastening. 17. A vehicle comprising: a strengthening member comprising a twelve-cornered cross section including sides and corners, the sides comprising eight straight sides and four curved sides, wherein a length of each straight side is the substantially the same and a radius of a curvature of each curved side is substantially the same;wherein the length of each straight side ranges from about 10 mm to about 200 mm and the radius of the curvature of each curved side ranges from about 3 mm to about 400 mm; wherein the ratio of the straight side length to the curvature radius ranges from about 0.9 to about 1.6. 18. The vehicle of claim 17, wherein the ratio of the straight side length to the curved side radius ranges from about 1.30 to about 1.35. 19. The vehicle of claim 18, wherein the sides and corners create twelve internal angles, wherein each internal angle is about 90 degrees. 20. The vehicle of claim 19, wherein an outer dimension of the cross section is substantially square-shaped.
