What does IB mean in ACADEMIC DEGREES

Impact bending is a type of mechanical testing that measures the resistance of a material to fracture under the application of a sudden, high-energy load.

Impact bending tests are important for evaluating the toughness and ductility of materials, which are critical properties for applications where materials are subjected to sudden loads or impact forces.

Impact bending tests are commonly used for testing metals, polymers, and composites. They can provide valuable insights into the material's ability to withstand impact loads and avoid brittle failure.

In an impact bending test, a specimen of the material is placed on a support and subjected to the impact of a pendulum or falling weight. The energy absorbed by the specimen during the impact is measured, and the material's toughness is evaluated based on the amount of energy required to fracture it.

There are various types of impact bending tests, including Charpy, Izod, and Dynatup, each with slightly different test configurations and specimen sizes. The choice of test type depends on the material being tested and the desired application.

Impact bending test results are typically reported as the energy absorbed by the specimen to fracture, which is expressed in joules (J). Higher energy absorption values indicate greater toughness and ductility of the material.

The results of impact bending tests can be influenced by factors such as the specimen shape and thickness, test temperature, loading rate, and material microstructure.
