Sheet sample impact test method

The invention provides a sheet sample impact test method which comprises the following steps: (1) shearing a plurality of sample blanks with the thickness of 5-10mm at adjacent positions of a cold-rolled sheet, stacking the sample blanks together to form a sample block, and fixing the sample block; (2) forming a notch with a V-shaped or semicircular structure at the edge of the middle part of the sample block; (3) carrying out an impact experiment on the sample block; and (4) dividing the experimental value of the sample block by the number of the sample blanks to obtain the impact absorption energy of the sample blanks. According to the invention, a plurality of thin plate sample blanks are stacked to form the sample block and are fixedly connected through the bolts, so that the sample block has enough thickness, the sample block can be partially broken during the impact test, the test result is ensured to be effective, finally, the data of the single thin plate sample blank are obtained, and the method is s
