The skin-pass elongation (44) is such that it results in a translation ratio (220) of 15% or more at the location of the alternating curvature (54), the translation ratio (220) being determined by the ratio across the thickness of the metal plate (10) between:
- the translation of the elastic zone (202) at the location of the maximum curvature of the alternating curvature (54); and
- half the thickness (12) of the metal plate (10). |
