The test was pivotal in understanding the fracture problems of ships during World War II. [2] [3] The test was developed around 1900 by S. B. Russell (1898, American) and Georges Charpy (1901, French). [4] The test became known as the Charpy test in the early 1900s due to the technical contributions and standardization efforts by Charpy.
The most common is the Charpy impact test, which uses a pendulum hammer (striker) to strike a horizontal notched specimen. The height of its subsequent swing-through is used to determine the energy absorbed during fracture. The Izod impact strength test uses a circular notched vertical specimen in a cantilever configuration. Charpy testing is ...
Augustin Georges Albert Charpy (1 September 1865 – 25 November 1945) was the French scientist who created the Charpy impact test. He attended École Polytechnique from 1885 to 1887 and graduated with a degree in Marine Artillery. In 1887 he became a professor at École Monge. In 1892 he published his physics thesis.
The Izod impact test differs from the Charpy impact test in that the sample is held in a cantilevered beam configuration as opposed to a three-point bending configuration. The test is named after the English engineer Edwin Gilbert Izod (1876–1946), who described it in his 1903 address to the British Association, subsequently published in ...
