According to current Charpy test standards (ASTM E23-12c and ISO 148-1:2009), absorbed energy (KV) results from partially fractured test specimens can be averaged with the results from fully fractured specimens. However, most researchers agree that if a specimen does not fully fracture at the end of a Charpy test, a significantspecimen to the deforming or breaking specimen is equated to the "impact energy." The Charpy impact test uses a standard Charpy impact machine to evaluate this impact energy. The machine consists of a rigid specimen holder and a swinging pendulum hammer for striking the impact blow to a v-notched specimen as shown in Figs. 1 and 2. The Charpy impact test relies on the potential energy of a weighted pendulum as shown in Fig. 1. The pendulum is raised to some initial height h i, .
