Split Hopkinson Pressure Bar (SHPB)
Split Hopkinson transmission Bar (SHTB)
Product Introduction
The Split Hopkinson Pressure Bar (SHPB), exclusively distributed by Marjan Polymer Industries in Pakistan, is an advanced piece of equipment designed to study the dynamic mechanical properties of materials under one-dimensional stress conditions. This device is crucial for determining the stress-strain characteristics of materials when subjected to dynamic impacts, making it an invaluable tool for both research and industrial applications.
Key Features of Split Hopkinson Pressure Bar
1. Dynamic Compression Testing
Purpose:
- The SHPB is used for dynamic compression loading measurements, enabling the study of materials under high strain rates.
Working Principle:
- A stress wave is generated in the incident bar, travels through the specimen, and is measured in the transmitted bar. This wave splits into transmitted and reflected waves, with strain gauges measuring the resulting deformations.
2. Bar Specifications

- Launch Barrel Length: 2600 mm
- Striker Bar Length Range: 100, 200, 300, 400, 600 mm
- Striker Bar Velocity: 50 m/sec
3. Pressure Tank and Strain Rate
- Pressure Tank Volume: 25 Liters
- Operating Pressure Range: Up to 4 MPa
- Strain Rate Range: 100 s-1 to 10000 s-1
- Setup Dimension: Up to 9 meters
4. Guiding and Measurement Systems
- Guiding Rail: Combination of multiple rails forming a unified system
- Speed Measurement: Optical sensor, measuring range 0-100 m/s
- Test Accuracy: 1%
5. Support, Damper, and Safety Features
- Bar Support and Alignment: Three-way adjustable support system
- Damper: Energy-absorbing material with mechanical buffering
