Experiment: Mechanical Testing- Impact & Hardness Testing

Two standardized tests, the Charpy and Izod, are commonly used to measure Impact Energy (sometimes referred to as Notch Toughness). The Charpy V-notch (CVN) technique is most commonly used in the United States. For both Charpy and Izod, a V-notch is machined into a bar specimen with a square cross-section.
