Impact Testing Through IZOD and Charpy Machines

1. Impact Testing Through IZOD and Charpy Machines Impact Testing plays an important role to study the toughness of the material. Material’s toughness is a feature that ensures the amount of energy absorbed to get deformed and ensures the strength and ductility of the product. For example, brittle material such as glass, ceramics has a low toughness factor that is why it gets deformed easily. Generally, the impact energy can increase or decrease with the variation of temperature. Hence, the temperature can vary the value of impact energy for every product. Generally Impact testing is done for the test specimens from Pipe, Laminates, Composites, Ceramics, etc. Understanding the energy absorption properties of the material is critical, But, through impact testing, it can be possible to count the impact value. And, for the best results, it is also important to understand the similarities and differences between two common impact test methods that are IZOD Impact Test and Charpy Impact Test. Working of IZOD Machine & Charpy Machine for Impact Testing Both the testing machines work on the same pendulum principle but different notches. These test methods are best to analyze the properties of the material in terms of strength or ductility. In the impact test, the amount of energy required or absorbed by the specimen is counted when a weighted pendulum or hammer hits them. This calculated energy explains the property of the specimen in terms of strength and ductility. Here is how these two testing machines work. As we discussed earlier, both the testing machines work in the same principle but on different notches, the IZOD machine follows the V-notch with vertical positioning of the specimen. On the other hand, the Charpy machine follows both U-

In the Charpy Test, the notch direction is positioned away from the striker and the hammer strikes the specimen at the point of the notch but in the opposite direction. Whereas, In the IZOD tests method, the hammer or pendulum strikes the specimen at the upper tip. To measure the impact value of the product, different industries have different requirements.
