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 . The impact tests employed in the research work were the Charpy V-notch impact test and the drop-weight tear test (DWTT). The impact tests have been correlated with full-size cylindrical vessel tests in which the initiation and propagation characteristics have been determined under controlled conditions.Impact tests are short-term tests which provide information on the failure behavior of materials or components subjected to rapid loading and at varying temperatures. The testing systems used for these tests are either pendulum impact testers or drop-weight testers.
There are basically two types of impact tests: pendulum and drop weight. Izod, Charpy, and tensile impact are the most common of the pendulum type tests. Pendulum Testing. The first attempts at obtaining this value were done by means of a swing pendulum. A pendulum of a known weight is hoisted to a known height on the opposite side of a pivot . Portable products can suffer critical damage due to drop impact and thus, such load cases must be taken into account in the conceptual and detailed design phases of such products. One method explored in the current study for alleviating the peak accelerations resulting from impact is to isolate fragile components from the product housing using internal shock .There are basically two types of impact tests: pendulum and drop weight. Izod, Charpy, and tensile impact are the most common of the pendulum type tests. What is impact testing machine? Impact testing machines evaluate an object's capacity to withstand high-rate loading and it is commonly used to determine the service life of a part or material.
