In forging industry, the Charpy impact test can be used to determine the malleability and ductility of a material that is being forged. In the rubber industry, the test can be used for determining the shock absorbing ability of a type of rubber so that its proper application could be decided. History of the Charpy impact test. The history of Charpy V-notch impact testing dates back to the early 1900s when French engineer Georges Charpy developed a standardized method for testing the impact toughness of materials, particularly metals. His work led to the creation of the Charpy impact test, which involved striking a standardized specimen with a .
The Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain-rate test which determines the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material's notch toughness and acts as a tool to study temperature-dependent ductile-brittle transition.The value of energy absorbed is read directly from a dial on the machine. A typical impact testing machine is shown in Figure. 1. Figure 1. Schematic of a Typical Charpy Impact Testing Machine. In carrying out a test, the specimen is loaded into the anvil with a pair of special tongs that facilitate location of the specimen in the machine. Charpy Impact Test. In a Charpy test, a notched specimen is struck by a pendulum hammer swinging from a known height. The energy absorbed by the specimen during fracture is calculated by the difference in the pendulum’s height before and after impact. This energy absorption measures material toughness.

There are two main forms of impact test, the Izod and the Charpy test. Both involve striking a standard specimen with a controlled weight pendulum travelling at a set speed. The amount of energy absorbed in fracturing the test piece is measured and this gives an indication of the notch toughness of the test material.

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.
charpy impact test results explained
The Izod impact test is similar to the Charpy impact test but uses a different arrangement of the specimen under test. The Izod impact test differs from the Charpy impact test in that the sample is held in a cantilevered beam configuration as .The most popular impact tests are the Charpy test and the Izod test. These two tests determine essentially the same material characteristics, but differ in the orientation of the test sample, which causes the sample to be stressed in different directions and involves a known weight released from a known height colliding with the sample in its test structure. 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.The overall purpose of this research is to explore the usage of an impact testing machine, specifically the Charpy Impact Test device, to better understand the principles behind impact testing in order to further develop engineering skills in materials selection.
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.
