Fig. 6From: Experimental study of strain fields during shearing of medium and high-strength steel sheetForce-displacement curves from shearing of medium strength material (a) and high-strength material (b). Clearances (expressed as fractions of sheet thickness h) and clamping configurations are indicated in the figure legend. The dashed part of a curve indicates that it was impossible to image the speckle pattern on the sheetBack to article page
