The Izod impact strength test is an ASTM standard method of determining the impact resistance of materials. A pivoting arm is raised to a specific height (constant potential energy) and then released. The arm swings down hitting a notched sample, breaking the specimen. The energy absorbed by the sample is calculated from the height the arm swings to after hitting the sample. A notche.In the notched bar impact test, a one-time force with a large load is applied to the metal specimen, resulting in multiaxial stresses. Tests are performed at high or low temperatures. The objective of the test is to accurately predict the .There are two main forms of impact test, the Izod and the Charpy test. Both involve striking a standard specimen with a controlled weight pendulum travelling at a set speed. The amount of energy absorbed in fracturing the test piece is .

notched impact strength test
In materials science, the Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain rate test which determines the amount of energy absorbed by a material during fracture.Absorbed energy is a measure of the material's notch toughness.It is widely used in industry, since it is easy to prepare and conduct and results can be obtained quickly and . ASTM E2248 – 18: Standard Test Method for Impact Testing of Miniaturized Charpy V-notch Specimens.; Ductile to brittle transition in impact testing. Carbon steel and low alloy steel are characterized by the fact that the fracture behavior changes as the temperature drops and the fracture type changes from ductility to brittleness.

In a Charpy impact test to ISO 148-1, a notched metal specimen is severed using a pendulum hammer. For the test, the metal specimen is centered on the supports in the pendulum impact tester. The notch is exactly across from the point at which the pendulum hammer strikes the specimen. This impact test is used to determine the absorbed impact energy. 1.1 These test methods describe notched-bar impact testing of metallic materials by the Charpy (simple-beam) test and the Izod (cantilever-beam) test. They give the requirements for: test specimens, test procedures, test reports, test machines (see Annex A1) verifying Charpy impact machines (see Annex A2), optional test specimen configurations . Scope: This standard specifies the requirements for notched-bar impact testing using both Charpy and Izod methods. It includes guidelines for specimen dimensions, preparation, and testing procedures. Specimen Dimensions: Charpy V-Notch: 55 mm length, 10 mm width, 10 mm thickness, with a 2 mm deep notch and a 45° angle.
The 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.Mechanical testing - Notched bar or impact testing - Part I The previous article looked at the method of Charpy-V impact testing and the results that can be determined from carrying out a test. This next part looks at the impact testing of welds and some of the factors that affect the transition temperature such as composition and microstructure.Impact test. Measures the ability of a material to absorb a sudden application of a load without breaking. The Charpy test is a commonly used impact test. Lateral expansion. The lateral change in dimension of a Charpy impact specimen due to fracture. The dimension measured is the width opposite the v-notch (see Fig. 1-3).
