Pendulum impact testing machine HIT750P - Charpy and tensile impact tests on metals. . While influences such as fracture speed and notch shape are an important part of the test, the main purpose of the Charpy pendulum impact test is to qualitatively compare the toughness of the same material at different temperatures.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 .
Tensile testing of composites is generally in the form of basic tension or flat-sandwich tension testing in accordance with standards such as ISO 527-4, ISO 527-5, ASTM D 638, . The Charpy impact test was invented in 1900 by Georges Augustin Albert Charpy (1865–1945), and it is regarded as one of the most commonly used test to evaluate the .Other frequently used impact tests include the Izod test and impact tensile test. Izod tests, developed by ASTM, are widely used in the North American region, while Charpy tests are more typically utilized in other parts of the world. Tensile impact tests determine a material’s impact energy under tensile loading.Impact test. Measures the ability of a material to absorb a sudden application of a load without breaking.
