Square cross sectional area, testing 2.5 - 3.3 radius of curvature with either 3.1cm or 3.3cm leg length, 0.35cm thickness 

Same as V0 but added support beam at the end of the radius of curvature 

Same as V0/V1 but support beam placed 3 mm below the end of the radius of curvature 

Decreased thickness to 0.3cm, beam placed at the end of the radius of curvature

Increased thickness to 0.325cm, beam placed at the end of the radius of curvature

Thickness remains 0.325cm, support beam moved above end of radius of curvature by 2mm

Thickness 0.325cm, support beam still 2mm above end of radius of curvature but support beam has been fillet

Radius of curvature a rectangular cross section while maintaining a square cross section for the legs, thickness 0.325cm

Radius of curvature a rectangular cross section while maintaining a square cross section for the legs, changed thickness to 0.315cm

Changed fillet of rectangular to square cross sectional area to reduce stress concentration, 0.315cm thickness

Rectangular cross sectional area is thicker while maintaining smooth fillet, 0.315cm thickness, 77.591mm across rectangular cross sectional area at top

Thinner at top rectangular cross sectional area, 76.188mm across rectangular cross sectional area at top, 0.315cm thickness

0.325cm thickness, thinner at top rectangular cross sectional area, 61.262mm across rectangular cross sectional area at top

0.285cm thickness, thinner at top rectangular cross sectional area, 49.201mm across rectangular cross sectional area, added 3.0cm radius of curvature

0.275 cm thickness, same design shape at top as V13, 49.201mm across rectangular cross sectional area at top

0.275 cm thickness, same design shape everywhere as V14, 49.201mm across rectangular cross sectional area at top, added a beam at 0.45 cm below the bottom edge of the curvature with no fillet

0.275 cm thickness, same design shape everywhere as V14, 49.201mm across rectangular cross sectional area at top, added a beam at 0.45 cm below the bottom edge of the curvature with fillet

0.275 cm thickness, same design shape everywhere as V14, 49.201mm across rectangular cross sectional area at top but added a beam at 0.35 cm below the bottom edge of the curvature
