Experiment No. 2 Charpy Impact Test Shiva Yadav Aerospace Engineering, 3rd Sem (Dated: August 10, 2022) This report is a summary of the experiment to determine the Toughness of materials known as the Charpy Impact Testing .
Charpy impact test results are measured in joules, the SI unit for energy. This is simply the amount of work performed by a 1-newton force pushing a sample by 1 m in the direction of the force. This value can be used to calculate the impact energy in J/m2 by dividing the joule value by the sample's cross-sectional area at the sample notch .

ENME 2711 SEC 001 Charpy Impact Test Laboratory Report Experiment I lab report .specimen to the deforming or breaking specimen is equated to the "impact energy." The Charpy impact test uses a standard Charpy impact machine to evaluate this impact energy. The machine consists of a rigid specimen holder and a swinging pendulum hammer for striking the impact blow to a v-notched specimen as shown in Figs. 1 and 2.steel plate would pass a Charpy impact test has been developed. This was done to prevent testing material that would not pass the required Charpy test, without having to sample the plate for grain size. Avoiding testing plates that would not pass would preclude loss of material and time, resulting in savings for the com- pany.
