Impact test is one of the conventional methods to evaluate the mechanical properties of metal materials. The purpose of the impact test is to understand its structural weaknesses and functional degradation, help to understand the product's structural strength and appearance resistance to impact, drop and other characteristics, effectively evaluate the reliability of the product and monitor the consistency of the product line. Impact test can also be used as a means of product satisfactory design and quality control. T, C&A Lab is most trusted name for testing impact resistance of materials, which has the capability of performing a variety of impact tests, including Charpy, IZOD, instrumental, drop-weight and dynamic tear testing.
The impact tests we provide include but are not limited to:
Charpy Impact Test
Charpy impact test is used to determine the notch sensitivity (toughness) of metal materials. The metal sample with a certain shape and size is prepared with U-notch or V-notch, which is in the state of simply supported beam on the Charpy impact tester. The pendulum raised by the testing machine is used to make the sample break along the notch, and the absorption work of the sample is calculated by re-raising the height difference when the pendulum is broken, that is, Aku and Akv. The impact test can be carried out at different temperatures.
IZOD Impact Strength Test
IZOD impact test is also called cantilever impact test. The IZOD impact strength test is an ASTM standard method of determining the impact resistance of materials. The test is similar to the Charpy impact test but uses a different arrangement of the specimen under test. It is used to study the behavior of notched specimens with specified size under specified impact force, and to estimate the degree of brittleness or toughness of hard materials under specified conditions.
Instrumented Impact Test
The instrumented impact test machine system uses a strain gauge instrumented impact hammer to measure the force applied during the impact, which has many advantages, the most important of which is the measurement of force and energy. The instrumented impact test can study the surface strengthening effect of the material, and the toughness and brittleness of the material can be measured by the ductile section rate.
Drop-weight test is an impact test method. The heavy hammer falls on the sample from different heights, and the relationship between the falling height and the damage rate of the sample is obtained. The drop height when the failure rate is 50% is used to express the impact resistance of the sample. It is a special impact test used to determine the non-plastic transition (NDT) temperature of steel.
Dynamic Tear Test
The dynamic tear test is a test in which a dynamic tear sample in a simply supported beam state is punched once on an impact testing machine to measure its absorbed energy and fiber section rate. Dynamic tear test is widely used to evaluate the crack growth resistance of metal materials and characterize the full range of transformation characteristics of materials.
