WebbCharpy Test Specimens Charpy test specimens normally measure 55x10x10mm and have a notch machined across one of the larger faces. The notches may be : V-notch – A V-shaped notch, 2mm deep, with 45° angle and 0.25mm radius along the base. U-notch or keyhole notch – A 5mm deep notch with 1mm radius at the base of the notch. Fig 2: … 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 … Visa mer In 1896, S. B.
