Webb16 mars 2005 · Impact energy is a measure of the work done to fracture a test specimen. When the striker impacts the specimen, the specimen will absorb energy until it yields. At this point, the specimen will begin to undergo plastic deformation at the notch. The test specimen continues to absorb energy and work hardens at the plastic zone at the notch. WebbThe four most common impact-test procedures in use around the world are probably ISO 148 “Steel— Charpy impact test V-notch ,” ASTM E 23 “Standard Test Methods for Notched Bar Impact Testing of Metallic Materials,” EN 10045 “Charpy Impact Test for Metallic Materials,” and JIS Z2242 “Method for Impact Test for Metallic Materials.”
