impact test, Test of the ability of a material to withstand impact, used by engineers to predict its behaviour under actual conditions.Many materials fail suddenly under impact, at flaws, cracks, or notches.The most common impact tests use a swinging pendulum to strike a notched bar; heights before and after impact are used to compute the energy required to fracture the bar .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.Instron manufactures tensile, compression, fatigue, impact, rheology, and structural testing machines, testing a variety of materials and range of applications. Telephone: +1 800 877 6674A pendulum impact testing machine is used to determine the impact strength or toughness of a material under impact loading by measuring the amount of energy the material is able to absorb. Knowing the energy absorption properties of a material is crucial for predicting how much plastic or permanent deformation the material can withstand before it fails.
Impact testing is classified according to how a material resists impact. The following are the different types of impact test machines: Charpy Impact Test: The Chapy impact test is a widely used method to determine the toughness of a material. In this test, a pendulum is swung by a weight on the top of a test sample to create an impact.

An automated hardness testing machine allows hardness to be measured relatively simply. To provide meaningful hardness readings for a wide variety of materials, from soft to hard. For some applications, the hardness of a material is the key characteristic that is valuable to know.IMPACT TESTING MATTERS, NOW MORE THAN EVER 1.1 What is a Pendulum Impact Test An impact test determines a material’s resistance to an impact event. It measures the amount of energy the material absorbs when it is hit by a high-rate load. The most common impact test methods are Charpy and Izod and are typically run using a pendulum impact tester.
Before looking at impact testing let us first define what is meant by 'toughness' since the impact test is only one method by which this material property is measured. Toughness is, broadly, a measure of the amount of energy required to cause an item - a test piece or a bridge or a pressure vessel - to fracture and fail.
Material impact toughness can be measured by various types of test such as the Charpy V-notch impact test, Izod test or K IC test. The most commonly used test is the Charpy impact test (see Fig. 6.9), which gives an indication of the toughness of a material at a specified temperature.It is not a particularly accurate test but can give a general indication of the ability .Apparatus for Aggregate Impact Test The apparatus as per IS: 2386 (Part IV) - 1963 consists of: (i) A testing machine weighing 45 to 60 kg and having a metal base with a painted lower surface of not less than 30 cm in diameter. It is supported on level and plane concrete floor of minimum 45 cm thickness. The machine should also have provisions .Instron Dynatup drop weigh impact testing machine next generation is the Instron 9400 Series. A drop weight impact testing machine is used to determine the energy required to break or damage a material in which a defined weight falls onto a specimen or a component from a specific height and with a specific impact energy and velocity.
Difference between a Pendulum Impact Testing machine and a Drop Weight Tester. Each test uses a different approach. As the name implies, a pendulum uses a hammer (mass) rotating on an axis to strike a sample. The point of . Prepare Report: Finally, a report can be prepared to note the test procedure, the standard used, and the test results. The Machine Used in Charpy Impact Testing. A Charpy impact testing machine is used to test the .A drop weight tester is a testing machine that is used to test the resistance of a material to impacts or shocks.In the drop weight impact test, a weight is dropped from a defined height onto the material to be tested using a drop weight tester. .
The factors responsible for the Charpy impact test are ductility, yield strength, notch, temperature, and fracture mechanism. Figure 3, shows the working procedure of impact testing. The pivoting arm is raised to a specific height, which is the potential energy and then this arm gets released.

This initial crack will ensure the crack propagates as intended. A universal testing machine can be used to carry out a fracture toughness test. This is useful as these machines can also carry out tensile testing.In accordance with to the ISO 180-2000 standard (ISO 180 2000), notched Izod impact tests are carried out.The impact behavior of polycarbonate specimens is analyzed. Rectangular plates of polycarbonate Lexan 141R, with dimensions 170 × 70 × 3.2 mm 3, are injection-molded.The melt temperature and the injection velocity are set to 295°C and 30 cm 3 /s respectively.The Universal Grip Company is the leading distributor of both Charpy and Izod impact testing machines in the USA. These premium machines are capable of both types of impact testing procedures. The impact testers have a motorized system for reloading the pendulum via a pushbutton which decreases the time in between test runs.
Izod Impact Testing Equipment. Instruments for testing plastics have been manufactured commercially since the 1940s, and there are several manufacturers of testing equipment that meet the requirements of ASTM D256. Over the years, the basic physical characteristics of the test machine have stayed the same, but the means of data acquisition .
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. 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.
