2.3.3. Impact test
The impact test specimens are prepared according to the required
dimension following the ASTM-A370 standard. During the
testing process, the specimen must be loaded in the testing machine
and allows the pendulum until it fractures or breaks. Using
the impact test, the energy needed to break the material can be
measured easily and can be used to measure the toughness of
the material and the yield strength. The effect of strain rate on fracture
and ductility of the material can be analyzed by using the impact
test.
The different specimens used for impact testing is presented in
