Testing Principle
The Split Hopkinson Pressure Bar (SHPB) operates based on one-dimensional stress wave theory to characterize material behavior under high strain-rate loading. A striker bar impacts the incident bar to generate an elastic stress wave, which interacts with the specimen between the incident and transmission bars. The incident, reflected, and transmitted waves are recorded by strain gauges. Using classical data reduction methods, the dynamic stress, strain, and strain rate of the specimen are calculated, enabling accurate analysis of material constitutive behavior under impact conditions for research and simulation validation.
