The Charpy impact test measures the energy absorbed by a standard notched specimen while breaking under an impact load.
The Charpy impact test used to determine the resistance capacity of metal (steel) specimen against sudden impact load of a pendulum which swung from a certain height. The other name of the Charpy impact test is the Charpy V-notch test because of the specimen used in this test cut at a certain depth in V shape.Characteristics of Charpy Impact Tests Using C-Notch SpecimensIn the present paper, the impact behaviour of C-notch specimens with notch radii of 2R, 5R and 10R was investigated in Charpy impact tests and compared with that of U-notch ones.
