Testing Principle
Incident Bar → Specimen → Transmission Bar
The Split Hopkinson Tension Bar (SHTB) system is based on one-dimensional stress wave theory. A tensile stress pulse is generated and propagated through the incident bar to load the specimen at high strain rates. Strain gauges mounted on the incident and transmission bars measure the elastic stress waves, allowing the dynamic stress, strain, and strain-rate response of the specimen to be accurately determined.
