The present invention relates to a shear material testing apparatus having a multi-stage shaft and a plurality of shear testing units arranged in a longitudinal direction. The shear material testing apparatus is used to conduct shear test operations regarding a plurality of materials at the same time. The shear material testing apparatus comprises: a pair of fixing shafts arranged in parallel and in a longitudinal direction; a pair of conveying shafts arranged to be parallel to the fixing shafts, and to slide in the longitudinal direction; a driving unit which slides the conveying shafts for the shear test of the materials; a sensor which outputs a shear force of the materials; and the shear testing units including a pin-shaped fixing unit fixated to the fixing shafts on a side, a pin-shaped conveying unit fixated to the conveying shafts on an other end, and a clamping jig which clamps the materials on the inside. According to the present invention, one testing apparatus includes the plurality of shear testing units to conduct shear tests for the plurality of materials, thus reducing a testing time. |
