(a–c) Area and number of V-cracks and (d–f) bending load as a function of bending angle for the Z, AS, and ZB steels. The bending angle range (44°–75°) of the dashed-line boxes of (d–f) is shown in (a–c). The four bending stages are indicated respectively by orange, yellow, light-blue, light-purple colors in these figures.
