Máquina de Charpy

The Charpy impact test is a standardized high deformation rate test that determines the amount of energy absorbed by a material during fracture. The energy absorbed by a material during fracture is a measure of a given material's toughness and serves as a tool to study temperature-dependent ductile-to-brittle transition. It is widely applied in industry because it is easy to prepare and perform, and results can be obtained quickly and economically. The test was developed around 1900 by S. B. Russell and G. Charpy. Known as the Charpy test early in 1900 due to Georges Charpy's technical contributions and standardization efforts, today it is used in many industries to test materials, for example, high-pressure vessel construction and bridge building, to determine how storms will affect the materials used.
