Impact Testing
An impact test is used to measure toughness, capacity to resist the energy of shock loading or a dynamic impact of a product. Samples inspected under this test method are then checked for signs of deformation, fracturing and ruptures.
One kind of impact testing apparatus comprises of a weighted pendulum with a hammer fixed on the end with the sample placed into a holding fixture. The pendulum is then released (from a known height), where an impact is made with the sample below with a sudden force. This collision causes energy absorption by the sample and that energy is measured using precise equipment to determine the fracture mechanics of the sample.
The results from impact testing are critical in understanding a sample toughness and predicts how much energy it will be able to withstand before complete failure. A materials toughness is extremely important for the applications of its future use, for example within the construction, industrial or military markets.
The two main types of impact testing using a pendulum are Izod and Charpy, both tests are very similar but there are notable differences:
- The Izod impact testing holds the sample vertically with the notch facing the pendulum.
- The Charpy impact testing holds the sample horizontally with the notch facing away from the pendulum.
