so that it has a U-shaped notch or a V-shaped notch, is in the state of a simple beam on a summer-specific impact tester, makes a shock with a pendulum raised by a test machine, causes the specimen to break along the notch, and calculates the absorption work of the specimen by re-raising the height difference Impact tests can be made at different temperatures. The absorption value (joule) is large, which indicates that the material has good toughness and is insensitive to gaps in the structure or other stress concentration conditions. In recent years, the materials of important structures tend to use V-shaped notch specimens, which can better reflect the notch effect, to do impact tests.charpy test machine
