Charpy and izod are two common hardness tests
WebThe Charpy impact test was invented in 1900 by Georges Augustin Albert Charpy (1865–1945), and it is regarded as one of the most commonly used test to evaluate the relative toughness of a material in a fast and economic way. The Charpy impact test measures the energy absorbed by a standard notched specimen while breaking under … WebAlthough two standardized tests, the Charpy and Izod, were designed and used extensively to measure the impact energy, Charpy v-notched impact tests are more common in practice. The apparatus for performing impact tests is illustrated schematically in Figure-I. The load is applied as an impact blow from a weighted pendulum hammer …
