EXPERIMENTAL ANALYSIS OF IMPACT STRENGTH AND COMPARISON OF IMPACT .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 of energy absorbed by the specimen during fracture. . When reporting the results of a Charpy test, the .This page introduces the Charpy impact test principle and methods; as well as evaluation methods, test piece standards, differences from the Izod impact strength test, and methods for measurement of the fracture surface. The 3D Solutions Library operated by KEYENCE introduces examples of shape measurement problems and the latest solutions for various industries, .According to current Charpy test standards (ASTM E23-12c and ISO 148-1:2009), absorbed energy (KV) results from partially fractured test specimens can be averaged with the results from fully fractured specimens. However, most researchers agree that if a specimen does not fully fracture at the end of a Charpy test, a significant
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. The Charpy impact test relies on the potential energy of a weighted pendulum as shown in Fig. 1. The pendulum is raised to some initial height h i, . Charpy impact energy results for normal concrete [40], UHPC [38 ,43445152], and other advanced cementitious composites [53,54]. The results of these studies are too few and varied to re-E23 Standard Test Methods for Notched Bar Impact Testing of Metallic Materials Figure 1.

The notch must be of specific dimensions and geometry to enable consistent results. Testing can be performed at both ambient and reduced temperatures, sometimes as low as -425F (254°C). Charpy Test Standards: Charpy impact testing is typically carried out following standards like ASTM E23, ASTM A370, or ISO 148. Although the test is more .Tensile impact test procedures. The tensile impact strength test was originally developed to overcome the deficiencies of flexural (both Izod and Charpy) impact test. All the test variables that have a high effect on the results, such as notch sensitivity, toss factor and specimen thickness, are eliminated in the tensile impact test.
