ORTEGA, Y.. Prueba de impacto: ensayo Charpy. Rev. mex. fís. E [online]. 2006, vol.52, n.1, pp.51-57. ISSN 1870-3542.

In this paper some interesting results of Charpy impact tests are presented. The increase in the impact velocity, the present of a sharp notch and the ductile-to-brittle transition with decreasing temperature have been treated in a didactic way, by analyzing the fracture behaviour of several metals and polymers.

Palavras-chave : Impact test; mechanical testing; materials treatment effects.
