EXPERIMENT 2 Impact Test 1. OBJECTVE 1.1 To know how the Izod and Charpy methods work in order to measuring impact strength of polymer materials. 1.2 To differentiate the impact strength amount between Polystyrene and ABS. 1.3 To distinguish samples with notch and without notch 2. INTRODUCTION
Impact Test The tensile test is normally performed at a low strain rate, at which the specimen is very slowly loaded and elongated. When a material is subjected to a sudden, intense blow, in which the strain rate is extremely rapid, the material may behave in a much more brittle manner than is observed in the tensile test. Impact testing serves to assess a material’s impact toughness, representing its resistance to impact forces. The ability to quantify the impact property is a great advantage in product liability and safety. This involves three main tests: the tensile impact test, the Charpy V-notch test, and the Izod impact test.1. Reasons for Impact Testing Impact testing is performed to determine the energy absorbed or the energy required to fracture a unit under test (UUT). Take for example a straight-line collision, such as a car crash. Using the work-energy principle .specimen to the deforming or breaking specimen is equated to the "impact energy." The Charpy impact test uses a standard Charpy impact machine to evaluate this impact energy. The machine consists of a rigid specimen holder and a swinging pendulum hammer for striking the impact blow to a v-notched specimen as shown in Figs. 1 and 2.

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.
An Izod impact testing apparatus — which is essentially identical to a Charpy impact testing machine — is used to determine Izod impact strength. The primary differences between the Izod and Charpy impact tests are the size of the test specimen, how it is restrained, and which side is struck by the pendulum hammer.charpy impact testing lab report - Free download as PDF File (.pdf), Text File (.txt) or read online for free.

Tensile impact test procedures. The tensile impact strength test was originally developed to overcome the deficiencies of flexural (both Izod and Charpy) impact test. All the test variables that have a high effect on the results, such as notch sensitivity, toss factor and specimen thickness, are eliminated in the tensile impact 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 .
