Impact Curves at Room Temperature

Instrumented Impact Test (separately cast test bars)

Instrumented Charpy test with un-notched test bars. The testing machine was constructed with static hammer blade instrumented with strain gages.

Machine: Zwick 50 J, pendulum velocity 3.9 m/s. The drop in recorded load in the initial part of the curve is caused by the test method and the equipment used.
