Izod Impact Test | Laboratory Practical | Structural MechanicsIn this video i have performed an laboratory test used to identify impact energy absorbing capa. The Izod impact test is a type of test that measures the relative toughness of a material. Toughness in this context correlates to the material’s capacity to absorb energy. The Izod and Charpy tests are the standard methods for impact strength testing. Operators use a Pendulum impact testing machine to perform both tests.An impact test consists of a striker hitting the test specimen to transfer a large force in a short time.You can use a drop tower or a pendulum tester to achieve such large forces.. A striker is dropped vertically from a height for a drop tower test and uses gravity to achieve the necessary impact energy. Similarly, in a pendulum test, the striker is fixed to an arm that swings like a .
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 .The Izod impact test is the most common test in North America. The figure below, from Mitsubishi Chemical Advanced Materials, depicts the Izod impact strength test apparatus. ASTM D256: A pendulum swings on its track and strikes a notched, cantilevered plastic sample. The energy lost (required to break the sample) as the pedulum continues on . How Charpy impact tests are performed. Specimen Preparation: A small, standardized specimen, usually a rectangular bar with a V-shaped notch machined on one side.The notch creates a stress concentration that promotes fracture when impacted. The test setup includes a pendulum hammer, a notched specimen holder, and a digital or analog .
If you opt for Izod impact testing, selecting the right specimen configuration is the next step. Options range from round to square specimens and single-notched to three-notched ones. Opting for the 3-notch specimen can be more cost .For the Izod test, pendulum hammers according to standard ISO 13802 are used with a nominal impact energy range from 0.5J to 50J and impact velocities of 3.5 m/s. The impact strength (resilience) is calculated directly by dividing the .
