Charpy Impact Test - an overview | ScienceDirect Topics

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 …

Drop Testing - Impact Drop Test Standards & Procedures ...

Freefall drop testing, for example, looks at a test sample's structural integrity after it has been dropped from a certain height and specific orientation(s). A tumble test machine, on the other hand, evaluates the bare product response to a semi-random repeated tumbling or rolling motion, rather than a fall from a substantial height.
