For metals, the most commonly used pendulum impact test is the Charpy test. For steel samples, the Tinius Olsen Charpy machine is used; the transition point is determined by a fracture energy of 4.15 kgm (40.7 J). For some metals with a low fracture energy, the smaller Instron Wolpert machine is preferred. For polymers and polymer composites, Izod impact tests are preferred. For all materials except for composites, notched specimens are used to increase the stress concentrations and consequently the probability of brittle fracture.JB-B series Impact Testing Machines are used to determine the impact toughness of metal materials under dynamic load. The pendulum of the machine can be raised or released automatically. They have the features of easy operation, high efficiency, safe and reliable. The machines are especially suitable for laboratory, metallurgy industry, machinery production, steel plant and other fields.
