Charpy notched
WebA Charpy impact test can be done to determine the ductility, toughness, and ductile-brittle transition temperature of plastics. Likewise, it can be done to find out the sensitivity of notched plastic specimens. The notches used for Charpy impact testing are V-notch and U-notch while the notch used for Izod impact testing is only V-notch. WebSep 30, 2024 · Firstly, by analyzing the response of Charpy V-notch specimen impacted by pendulum, the relationship between specimen geometry, material properties, and impact energy is established and simplified, and the mathematical model for evaluating impact energy of specimens with different sizes is established.
