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.
The Charpy impact test measures the energy absorbed by a standard notched specimen while breaking under an impact load. This test continues to be used as an economical quality control method to determine the notch sensitivity and impact toughness of engineering materials such as metals, composites, ceramics, and polymers.
Charpy impact tests provide characteristic values for the impact strength of a material at high strain rates in the form of a surface area related energy value. The tests are normally performed at ambient temperature or a low temperatures.
9 sty 2022 · The Charpy impact test, introduced by Georges Augustin Albert Charpy (1865–1945) in 1901, is widely utilized for efficiently evaluating the toughness of materials. This method assesses the energy absorbed by a standard notched specimen when it fractures under an impact load.
13 lip 2018 · 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.
23 wrz 2024 · The Charpy impact test, performed according to EN ISO 148-1, involves the use of a pendulum hammer that strikes a notched metal specimen. The specimen is placed on special supports and the notch is oriented toward the point of impact.
