WebThere are several common hardness tests: Rockwell, Brinell, Vickers, Knoop, and variations within these tests. In general, these tests measure the resistance of the metal to an indenter. The indenter may be a ball, a pyramid, or a cone pressed into the metal surface under a given load. WebThe Charpy impact test is carried out in a 3-point flexure setup. The Charpy specimen is centered on the supports in the pendulum impact tester and rests against two anvils. In the case of notched specimens, the notch faces away from the pendulum hammer and is placed exactly across from the point at which the hammer strikes the specimen. javascript programiz online
