In materials science, the Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain rate test which determines the amount of energy absorbed by a material during fracture. Absorbed energy is a measure of the material's notch toughness. It is widely used in industry, since it is easy to prepare and conduct and results can be obtained quickly and cheaply. A disa… WebMar 20, 2024 · The Charpy Test Specimens can have one of three different types of notches used a ‘keyhole’, a ‘U’, and a ‘V’. For brittle materials (e.g., cast iron) keyholes and U-notch are suitable. For welding tests and ductile materials, the Charpy V-notch or also called CVN specimens are used worldwide.
