Abstract. The paper presents a novel experimental and numerical methodology for calibration of out-of-plane shear behaviour of moderate thick sheet metals by double bridge shear test. By conducting tests, it is shown that shear response of sheet metal in all three principal material planes can be characterised by the same specimen design with the shear detail or material oriented in a specific direction. For a 2.4 mm thick AA5754-H22 sheet material it is shown that the shear response is the highest in the rolling-transverse (RD-TD) plane, followed by the transverse-normal (TD-ND) plane, and the lowest in the rolling-normal (RD-ND) plane.
