Old vs. New: Instrumenting the Charpy Impact Test (VIDEO)

National Institute of Standards and Technology (NIST)

Caption

A Charpy test determines the impact toughness of metal samples by striking them with a swinging mass. The traditional test method requires measuring the difference between the height of the striker before and after impact. An instrumented striker, on the other hand, has force sensors on the striker's edge, allowing scientists to record the force on the sample through impact. This helps researchers to more precisely determine the impact toughness and ductility of various metals.
