WebFor the assessment of material toughness, international standards commonly require Charpy V-notch (CVN) impact testing of the steel product. A required toughness level is commonly expressed for a … WebCharacterizing the toughness of a material is done in several ways. The most common method is the notched-bar impact test for which two types of specimens prevail, Charpy and Izod. By subjecting a specimen to an impact load, it will fail if the load exceeds the breaking strength of the material.
