AA 5059 315 408 113 9.9 . The Charpy impact test (Charpy V-notch test) is used to measure the toughness of materials under impact load at different temperatures! Test setup and test procedure. In the Charpy impact test, a notched specimen is abruptly subjected to bending stress. The specimen is usually 55 mm long and has a square cross-section with an edge length of 10 mm. The Charpy impact test behavior of base metal, weld metal, and heat‐affected zone for 6061‐T6 and 7075‐T651 aluminum alloy welds was analyzed.How to Use Charpy Impact Test Results. Once the Charpy impact tester completes the test, the results are typically presented as the amount of energy absorbed during the fracture, measured in joules. These Charpy impact test results help manufacturers and engineers determine whether the material is suitable for its intended use. 1. Energy Absorption
The Charpy V-notch impact is a mechanical test for determining qualitative results for material properties and performance which are useful in engineering design, analysis of structures, and materials development. EQUIPMENT • Charpy V-notch test pecimens of 6061-T6 aluminum and 1018 (hot rolled) or A36 steelTable 3 shows the results obtained during the Charpy Impact Test of Aluminium specimen. Table 4 shows the results obtained during the Charpy Impact Test of EN3 specimen. The impact test is a method for evaluating the toughness, impact strength and notch sensitivity of engineering materials. Engineers test the ability of a material to withstand impact to predict its behavior under actual conditions. Many materials fail suddenly under impact, at flaws/cracks or notches. The most common impact tests use a swinging .
