Charpy Impact Test

The 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 an impact load. This test continues to be used as an economical ...
