HIKI delivers and transfers technology of Split Hopkinson Pressure Bar testing system to customers

15/10/2024

In the field of materials science, testing and evaluating the mechanical properties of materials under high dynamic loading conditions is extremely important. The Split Hopkinson Pressure Bar (SHPB) system of HIKI TEC., JSC, provides an advanced and effective solution for this testing.

The SHPB system operates on the principle of generating stress waves in a metal bar and measuring the response of the material sample as this wave passes through. Specifically, the system consists of two straight bars, called the incident bar and the transmitted bar, with the material sample placed between these two bars.

Incident wave: The stress wave is generated at the end of the incident bar and transmitted to the material sample.

Reflected wave: When the incident wave encounters the material sample, it will split into two smaller waves: the transmitted wave and the reflected wave. The reflected wave returns to the incident bar.

Transmitted wave: The wave passes through the material sample and into the transmitted bar, causing plastic deformation in the material sample.

We have developed the SHPB system with advanced features, including:

Compression and tensile testing capabilities: The system can perform both compression and tensile testing, meeting the diverse needs of materials research.

High temperature testing: The system can test material samples at high temperatures, helping to evaluate the mechanical properties of materials under harsh conditions.

High accuracy: The system is equipped with modern sensors and measuring devices, ensuring high accuracy in measurements.

The material testing solution with the SHPB system of HIKI TEC., JSC brings many significant benefits:

Data collection: The system provides accurate and detailed data, helping researchers easily identify and fix problems related to materials.

Durability and reliability: The system's devices are designed to operate stably under harsh conditions, ensuring that measurement results are not affected by the environment.
Wide Application: The solution can be applied to a wide range of materials and industries, from automotive to construction and aviation.

Here are some specific applications of this solution:

1. Testing the mechanical properties of metallic materials

The SHPB system is widely used to test the mechanical properties of metallic materials such as steel, aluminum, iron and copper. These materials are often used in industries such as automotive, aerospace and construction, where mechanical properties under high dynamic loading conditions are key.

2. Research on Polymer and Composite Materials

SHPB is also applied to research on soft materials such as polymers and composites. Special techniques of SHPB enable accurate measurement of the behavior of these materials under high loading conditions, including data reduction methods and temperature control to measure the uniaxial stress response of polymers and other soft materials.

3. Geomaterial Testing

The SHPB system is also used to test geomaterials, helping to determine the mechanical properties of soils, rocks and other natural materials. This is important in geotechnical and civil engineering studies, where understanding the mechanical properties of soils and rocks is a key factor in ensuring the safety and efficiency of construction works.

4. Stress and strain analysis

SHPB allows for the analysis of stress and strain of materials under high dynamic loading conditions. This helps researchers better understand how materials respond to rapid and strong impacts, thereby developing new materials with superior mechanical properties.

5. Applications in safety testing

Materials tested with the SHPB system are often used in safety-related applications, such as in the automotive industry to test the impact resistance of vehicle components. This helps ensure that the final products meet the highest safety standards.

6. New material development and testing

The SHPB system is an important tool in the development and testing of new materials. Researchers can use the system to test new materials under high dynamic loading conditions, thereby determining their mechanical properties and their applicability in practice.

HIKI TEC., JSC's SHPB material testing solutions bring many important applications to materials research and development. From testing the mechanical properties of metals and polymers, to geomaterials research and stress analysis, the SHPB system plays a key role in improving the quality and performance of materials.
