Impact Testing

Impact testing is an essential method used in material science and engineering to evaluate materials. It is also an important tool for materials testing and quality control, because it provides critical information about the behavior of materials under high velocity impacts. Using impact testing, the energy required to break the material can be easily measured and can be used to measure the toughness and yield strength of the material, which is critical when designing and constructing structures and components subjected to impact loads.

Our Test Projects

The most common method for alloy impact testing provided by Alfa Chemistry is the Charpy impact test. Here is a brief introduction to the test project.

Charpy Impact Test

The Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain rate test. The Charpy impact test measures the energy absorbed by a standard notched specimen while breaking under an impact load. The test specimen (dimensions, 10 mm × 10 mm × 55 mm; 45-degree V-notch with a depth of 2 mm and a root radius of 0.25 mm) is impacted by a pendulum at the opposite end of the notch. The absorbed energy required to produce two fresh fracture surfaces is recorded in joules ^[1]. The test is widely used as an economical quality control method to determine the notch sensitivity and impact toughness of alloy materials.

Advantages

The advantages of Charpy impact testing include, but are not limited to the following.

Quick and easy to perform: The Charpy impact test uses a relatively simple setup and thus results can be obtained quickly and cheaply. This makes it a cost effective method for measuring impact toughness.

Provides valuable information: Charpy impact testing can provide valuable information about the strength and toughness of a material under impact loading, which is important for applications where the material may be subjected to sudden or unexpected impacts.

Standardized test method: Charpy impact testing is a standardized test method, which means that the results are comparable across different laboratories and test conditions. This makes it a reliable method for evaluating materials.
