WebJul 1, 1995 · The effect of crack depth to specimen width, a/W, ratio on CTOD toughness was studied for a/W ratios of 0.2 and 0.5. Experimental testing also included Charpy V-Notch (CVN) impact tests at equivalent CTOD temperatures and tension tests of each of the simulated microstructures with 39.4 Kj/cm (100 Kj/in) heat input. WebAs was written, toughness can be measured by the Charpy test or the Izod test. These two standardized impact tests, the Charpy and the Izod are used to measure the impact energy (sometimes also termed notch toughness). The Charpy V-notch (CVN) technique is most commonly used. Both of these tests use a notched sample of a defined cross-section.
