Introduction

1. Standard Overview

GB/T 34108—2017 is a standard method for room temperature compression testing of metal materials under high strain rate ($10^{2}~\mathrm{s}^{-1} \sim 10^{4}~\mathrm{s}^{-1}$). This standard is mainly used to evaluate the mechanical properties of materials under dynamic loading, including key parameters such as yield strength and failure strain.

2. Test Principle

This standard is based on one-dimensional elastic stress wave theory and uses a split Hopkinson bar system for loading. By measuring the signals of the input wave, reflected wave and transmitted wave, the compressive stress-strain curve of the sample is calculated in combination with the material parameters.

3. Key technologies and equipment

Technical requirements	Equipment composition	Material parameters
Waveguide rod coaxiality test	Separate Hopkinson pressure bar system	Elastic modulus, density
Strain gauge calibration	Dynamic strain gauge and data acquisition device	Wave velocity, stress wave propagation time
Waveform processing	Data testing system	Compression strain rate, stress-strain curve

4. Implementation suggestions

Case Study: When testing Q235 steel, the compressive stress-strain curve was obtained by a split Hopkinson bar system. The calculation results show that at high strain rates, the yield strength is $455~\mathrm{MPa}$ and the average plastic strain rate is $2050~\mathrm{s}^{-1}$.

Note: The accuracy of equipment calibration and data acquisition must be ensured during the test. If waveform anomalies (such as limiting or distortion) occur, it is recommended to check the wire connections and sampling frequency settings.
