On an Impact Testing Machine of Drop Hammer Type
journal of the Japan Society for Testing Materials, 1961 In order to research on the behaviors of destruction of carbon steel forgings by impact bending, we designed an impact testing machine of drop hammer type. The total height of this testing machine is about 5m. The weights of the used drop hammers are 12.5, 25 and 50kg respectively. The maximum distance from the position of test piece to the drop hammer
