Charpy impact test
= Charpy impact test
{c}
A pendulum impact test on a specified notched specimen, commonly used to measure absorbed energy as a function of <temperature>. A transition curve characterizes a <ductile-to-brittle transition>, but its energy is not itself a <fracture toughness> value.<NIST Software Package for Obtaining Charpy Transition Curves by Enrico Lucon and others>[§2, Background: measured transition quantities and their dependence on temperature]{ref}
