Charpy impact test

Charpy impact test
A test of the impact strength of a material, used to determine its relative ductility or brittleness. The test is executed by swinging a large, heavy hammer on a pendulum from a predetermined height. The hammer fractures the material sample, usually a block of a certain size with a notch cut in it. The height to which the pendulum swings is used to calculate the energy necessary to fracture the sample. <!yes, this definition is long, but I dont think Ive included anything thats not essential, and theres no Wikipedia article just yet.
