Charpy Impact Tester

Simulate the ASTM E23 pendulum impact test to determine material toughness and the ductile-to-brittle transition temperature (DBTT).

Specimen Temperature20°C
Brittle (-60°C)Ductile (80°C)
Impact Energy (KV): Calculated from potential energy difference of the pendulum before and after fracture: KV=mg(hh)KV = m \cdot g \cdot (h - h').
