charpy impact test sample
The main objective of this experiment is to introduce two important basic mechanical property tests; hardness (using Rockwell testing) and impact (using Charpy testing). Chauvenet’s Criterion will be applied to identify outliers and probability paper will be used to ascertain whether or not the repeated measure hardness data isThe 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.The Izod impact test differs from the Charpy impact test in that the sample is held in a cantilevered beam configuration as opposed to a three-point bending configuration. Westmoreland Mechanical Testing & Research also offers a line of Instrumented Impact Testing designed to simulate real life rapid energy absorption conditions caused by .
The Charpy impact and notched impact test to ISO 179-1 and ISO 179-2 provide characteristic values for impact strength at high strain rates in the form of an area-related energy value. The tests are normally performed in normal climate or at low temperatures. Applications include: The comparison of different molding materials
