Charpy notched
WebThe Charpy impact test is a destructive test method that is used for the characterization of a material at high strain rates. It is performed on plastics as well as metals. Charpy impact tests provide characteristic values for the impact strength of a material at high strain rates in the form of a surface area related energy value. WebNotch angles of 45°, 60°, 75° and 90° were chosen for a standard charpy impact test specimen containing two such notches positioned at right angles to the applied load. For a given angle of the notch the dynamic fracture toughness increased with an …

In mechanical engineering and materials science, a notch refers to a V-shaped, U-shaped, or semi-circular defect deliberately introduced into a planar material. In structural components, a notch causes a stress concentration which can result in the initiation and growth of fatigue cracks. Notches are used in materials characterization to determine fracture mechanics related properties such as frac… WebWhat is a Charpy pendulum impact test? A test for determining toughness, or the tendency of a material to resist breaking on being subjected to sudden shock.
