Fig. 1From: Strain and stress conditions at crack initiation during shearing of medium- and high-strength steel sheetSchematic representation of the shearing geometry and boundary conditions. The moving tool and corresponding clamp have the same velocity v in the y-direction. Reaction forces on the moving tool as result of the velocity v are F x and F y . Definitions of sheet thickness h, clearance c, radius of the tool arc r and tool displacements U x and U y are shown in the magnified area (Gustafsson et al. 2014)Back to article page
