Izod impact test
A method for evaluating the impact value when one end of a test specimen is fixed and the opposite side is struck with a hammer from the direction of the notch, causing it to break.
Impact testing is a test that measures the resistance of a material when subjected to a high-speed load. There are several types of impact tests, including the pendulum-type Izod impact test, Charpy impact test, tensile impact test, and drop weight impact tests such as the Du Pont impact test and dart impact test. The Izod and Charpy impact tests typically involve notching the test specimen. By introducing a notch, stress concentration occurs, which is influenced by the notch shape and the method of notch fabrication.
