This test has been used almost exclusively with -centered-cubic (bcc) crystalline body materials. These materials show a transition from ductile to brittle behavior with temperature (Figure 2-2). This means that at low temperature the fracture energy is low.
In materials science, 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. Absorbed energy is a measure of the material's notch toughness. It is widely used in industry, since it is … See more In 1896, S. B. Russell introduced the idea of residual fracture energy and devised a pendulum fracture test. Russell's initial tests measured un-notched samples. In 1897, Frémont introduced a test to measure the same … See more The quantitative result of the impact tests the energy needed to fracture a material and can be used to measure the toughness of the … See more According to ASTM A370, the standard specimen size for Charpy impact testing is 10 mm × 10 mm × 55 mm.
