Charpy impact testing can also be used to determine the sensitivity of notched plastics specimens. Impact resistance of plastic notched specimens measures .
The Charpy impact test, also known as the Charpy V-notch test, is a high strain-rate test that involves striking a standard notched specimen with a controlled weight pendulum swung from a set height. The impact test helps measure the amount .
measuring impact energy are: Charpy Test and Izod Test.Charpy impact test is a low-cost and reliable test method, which is commonly required by the construction codes for fracture critical structures such as bridges and pressure vessels. Charpy impact test was developed in the 1960's as a method of determining the relative impact strength of .Charpy impact test specimens are cut from metal samples, and a V-notch is placed in the center. Charpy impact testing can be performed at ambient and low temperatures (down to -196°C). Low temperature charpy testing involves placing the specimens into a cooling chamber bath, and leaving specimens while a calibrated thermocouple records the .
