Fig. 10From: Strain and stress conditions at crack initiation during shearing of medium- and high-strength steel sheet a–f Experimentally based von Mises stress (Eq. (1)) fields at crack initiation for the medium-strength material using one clamp (left panels) and two clamps (right panels). The fringe levels are in gigapascal. Clearances, expressed as fractions of sheet thickness h, are indicated in each panelBack to article page
