George Charpy mengadakan pengujian tertulis dengan menggunakan [[Bandul|pendulum]] untuk mengetahui jumlah energi yang terserap selama fraktur. Kontribusinya yang besar secara teknis membuat penamaan pengujian impak hanya dikreditkan ke George Charpy dan tidak dengan Samuel Bridgman Russell.<ref>{{Cite web|title=The Evolution of the Charpy V-Notch Test|url=https://atrona.com/charpy-impact-test-history.html|website=ATRONA Test Labs, Inc|language=EN|quote=The impact-pendulum test method and associated equipment in nearly its current form was first developed more than a century ago. And while the basic concept behind this testing method is generally credited to two different engineers, S. B. Russell (1898) and G. Charpy in (1901); the test is now known by only the latter's name. The reason for this is due in large part to Georges Augustin Albert Charpy's technical contributions in the first half of the 20th century. These efforts included writing testing procedures in the use of a pendulum to apply an impact force to a specimen and measure the amount of energy absorbed during its fracture.|access-date=2023-06-20|archive-date=2023-06-20|archive-url=https://web.archive.org/web/20230620080408/https://atrona.com/charpy-impact-test-history.html|dead-url=no}}</ref> Meskipun uji impak Charpy dikembangkan pada abad ke-19 Masehi, uji impak Charpy masih digunakan hingga abad ke-21.<ref name=":0" /> Pemakaian uji impak Charpy umumnya lebih umum diterapkan di Amerika Serikat.{{Sfn|Zainul|2021|p=48}}
