WebNov 23, 2024 · This test method deals with the standard sampling procedure for impact testing of structural steel. Covered are the procedures for longitudinal Charpy V-notch … WebHow do you calculate Charpy impact value? The Charpy impact value (kJ/m2) is calculated by dividing the fracture energy by the cross-section area of the specimen. A test specimen having a V-shaped notch is fixed vertically, and the specimen is broken by striking it from the same side as that of the notch by the use of the hammer.
