Definition

The mechanical energy (typically reported in joules) absorbed by a standardized specimen during fracture in a Charpy V‑notch pendulum impact test; measured as the difference between the pendulum's initial and residual potential energy and used as a comparative indicator of a material's resistance to rapid, notch‑sensitive fracture under the specified test geometry, strain rate and temperature.
