Effects of the Striking Edge Radius on the Charpy Impact Test

Source

Effects of the striking edge radius of the Charpy impact test on the absorbed energy and the abrasion of the striker were investigated. The absorbed energy of the 8mmR was higher than that of the 2mmR when the absorbed energy was above 200N-m. The cause of this difference is that the bending deformation of the test specimen and the friction between the anvil and the test specimen are large in case of the 8mmR. The abrasion of the 8mmR striker was extremely large and it is too difficult to maintain the radius dimension according to ASTM E 23.
